Twinned Spell doesn’t actually make you “cast two spells”, it just says that:
When you cast a spell ... you can ... target a second creature in range with the same spell (1 sorcery point if the spell is a cantrip) (PHB 102)
Note that the text says that it is the same spell. You can't concentrate on two spells as you say, the first spell's concentration ...
Put him in armor he's not proficient in.
In 5e you cannot cast spells while wearing armor you're not proficient in. So unless the sorcerer has dipped Fighter and is therefore proficient in all armor (one of the quirks of 5e), wearing armor he's not proficient in renders him unable to cast spells. Plus, the armor makes it more difficult for him to escape ...
No, metamagic only takes effect when you cast the spell
All the sorcerer's metamagic abilities have wording like:
When you cast a spell that...
If you failed to cast the spell, you don't get to invoke the metamagic ability in the first place, so spending sorcery points is contingent on successfully casting the spell in the first place.
The rule on spellcasting does not say that you need a component, but:
Each spell's description indicates whether it requires verbal(V), somatic(S), or material(M) components. (PHB 203)
So technically there could be a spell that does not list any components. Subtle spell overwrites even the above rule, which it can do as a class ability is more specific ...
No, you can't counterspell spells with no components
Subtle spell is meant to protect against counterspelling.
Subtle Spell is meant to protect a spell w/o material components from counterspell, since you can't see the casting.
(from a tweet from Jeremy Crawford)
How many Sorcery Points should this cost? Lots. At least 5, since this metamagic is better than Careful Spell, Empowered Spell and Heightened Spell combined. I'm sure you can see where I'm going with this - it's too powerful to put a realistic cost on it.
Your new metamagic option does 3 things. The first is pretty simple - it multiples damage by 1.25, or 1....
The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell.
This says nothing about metamagic, so that aspect of the spell casting should be "treated as if you cast the spell." In effect, the ring doesn't store anything other than the spell's name, slot,...
Quickened Spell only affects the initial casting of the spell; it has no effect on actions granted by the spell
The Quickened Spell Metamagic, as you quoted, does exactly what it says: it changes the casting time of the spell from an Action to a Bonus Action. It does not do anything else.
The effect of Witch Bolt, which includes the ability to continue to ...
Scrap It Completely
This ability is ridiculously complex - it involves four die rolls of five dice, multiplication, and division... and all of this before the DM even rolls any saving throws. This is going to be a nightmare to adjudicate at the table, and no DM I've ever encountered will have decided on enough positioning detail at the kinds of range you'd ...
It'll work, just not the way you described.
Why your plan won't work
In your plan, you are trying to cast two bonus action spells. One is a standard cast of a Bonus Action (Healing Word) and the other is a spell converted from Action to Bonus Action via Quicken (Eldritch Blast.)
Unfortunately, you only get one bonus action per turn.
You can take only ...
If the spell is on your class’s spell list, you can read the scroll and cast its spell without providing any material Components. Casting the spell by reading the scroll requires the spell’s normal Casting Time. If the spell is on your class’s spell list but of a higher level than you can normally cast, you must make an ability check ...
Using Twinned Spell only uses one spell slot. This is because you are not casting two spells, rather you are making a single spell hit more than one target.
"...target a second creature in range with the same spell..."
However, it's worth noting that you can't cast Fireball with Twinned Spell.
Quote from PHB page 102 (emphasis mine)
Twinned Spell: ...
Yes, they will still take half damage.
This doesn't contradict the text at all, because you have successfully protected them from the full force of the spell. You aren't able to protect them completely, but they haven't taken the full damage the spell would have otherwise inflicted.
No, you can't. In general, you can only use one metamagic, once, on any spell.
The only such note is this one, on Empowered Spell:
There's a simpler way to do this.
What you need is a template in a hexagonal pattern surrounding a central hex. Adapt the scale/size of the hexes to suit the spell, and all you need is two die rolls: 1d20 and 1d6.
The mechanics of your meta magic...
... would look something like this:
Spend the meta magic points.
Succeed or fail on a DC check to ...
The newly released errata for the PHB answers this question definitively:
If a Wild
Magic effect is a spell, it’s too wild to be
affected by Metamagic. If it normally requires concentration, it doesn’t require
concentration in this case; the spell lasts
for its full duration.
So you can't use any form of metamagic on spells cast by your Wild ...
The Metamagic Option, Distant Spell, if used, changes the range of the spell from touch to 30 ft (PHB 102).
Conversely, Find Familiar (PHB 240) gives you the option when you cast a spell with the range of touch to cast it through the familiar, using its reaction to cast the spell.
The two effects are mutually exclusive. If you spend the sorcery point, it ...
RAW both effects apply, but it's not clear if the range should be 480 or 360. It depends on if you interpret double as "x2" or "+100%". While previous editions of the game made it clear that "doubling a double is a triple," as far as I can tell 5e doesn't tell you what to do either way.
However, this exact question was asked to Jeremy Crawford on Twitter, ...
It depends on how you define "targets only one creature"
When you cast a spell that targets only one creature and doesn't have a range of self [...] To be eligible, a spell must be incapable of targeting more than one creature at the spell’s current level.
To answer this, we need to drill down and answer thoroughly what a "target" is in 5th edition D&...
You can't twin hex
Twinned spell states (as of the first official errata):
To be eligible, a spell must be incapable of targeting more than one creature at the spell’s current level.
Hex is able to target more than one creature if the first one dies so it is ineligible. This targeting is referred to as "curse"ing but the effect is the same.
A typical ...
Yes, Simulacrum can be twinned
It creates one duplicate each of two creatures.
Just to take the first line of the Simulacrum spell:
You shape an illusory duplicate of one beast or humanoid that is within range for the entire casting time of the spell.
The target is one beast or humanoid within range touch.
There's nothing logically stopping this from ...
Yes, because the spell is still a melee spell
Looking at Sage Advice (see quote below) the Distant Spell Metamagic just adds a range of 30ft as you've said, but the spell is still considered a melee spell, thus a melee attack so you can add the 1d6 fire damage to it.
@JeremyECrawford If you use distant spell on a touch spell like shocking ...
Xanathar's Guide to Everything has optional rules for this situation

If the need for a spell’s components has been removed by a special ability, such as the sorcerer’s Subtle Spell feature or the Innate Spellcasting trait possessed by many creatures, the casting of the spell is ...
Twinned Spell says:
When you cast a spell that targets only one creature [...]
With the release of the errata for the PHB, we have this additional restriction:
To be eligible
for Twinned Spell, a spell must be incapable of targeting more than one creature at
the spell’s current level.

Yes, as long as the cantrip has a casting time of 1 Action
Most cantrips require an action to cast. As such, you can certainly quicken them. So any 1 Action casting time cantrip will be usable, such as Eldritch Blast in this question.
However, PHB p. 202 states:
A spell cast with a bonus action is especially swift. You
must use a bonus action on your ...
First: There isn't an equivalent.
Wizards cannot, by Rules-as-Written, get Metamagic. They just don't have access.
But, don't worry, there's a few things you might be able to do.
1. Three Sorcerer levels
Taking Three levels in Sorcerer (provided your DM allows you to Multiclass) grants you access to the Subtle Spell metamagic. You'll have three points ...
You cannot twin any of these spells
Eyebite has a range of self so it is explicitly disallowed when twinning as per the Twinned Spell description:
When you Cast a Spell that Targets only one creature and doesn’t have a range of self...
Bigby's Hand and Telekinesis do not target a creature, but rather each create an effect, which can then target a ...
RaW, yes, the spell could still be countered.
If the spell has a material component, you're not able to hide it. Nothing in the RaW claims that you can hide the casting of a spell by using a small arcane focus or something else. In fact, from XGtE, p. 85, "Perceiving a Caster at Work":
To be perceptible, the casting of a spell must involve a verbal, ...
