You're level 8 for the purposes of the multiclass spellcaster table.
Spell Slots. You determine your available spell slots by adding together all your levels in the bard, cleric, druid, sorcerer, and wizard classes, half your levels (rounded down) in the paladin and ranger classes, and a third of your fighter or rogue levels (rounded down) if you have the Eldritch Knight or the Arcane Trickster feature. Use this total to determine your spell slots by consulting the Multiclass Spellcaster table.
3 Bard + 1 Cleric + 1 Druid + 1 Sorcerer + 1 Wizard + (Paladin 1 + Ranger 1) / 2 = 8. Warlocks are not included, and you don't have enough Fighter or Rogue levels to count as more than 0.
Your Pact Magic spell slots from the Warlock class are separate, but can be used to cast spells from other classes:
Pact Magic. If you have both the Spellcasting class feature and the Pact Magic class feature from the warlock class, you can use the spell slots you gain from the Pact Magic feature to cast spells you know or have prepared from classes with the Spellcasting class feature, and you can use the spell slots you gain from the Spellcasting class feature to cast warlock spells you know.
So, just to be clear, you have:
- two 4th-level slots,
- three 3rd-level slots,
- three 2nd-level slots, and
- four 1st-level slots from your combined Spellcasting features, and
- one 1st-level spell slot from your Pact Magic feature as a Warlock.
You can cast any spell you have from any of your classes using any of your spell slots, as long as the level of the slot is greater than or equal to the level of the spell. Your Pact Magic slot will be recovered by a short rest, where all your other slots are recovered by a long rest. Your Arcane Recovery from your Wizard class will regain one 1st-level Spellcasting feature slot when used.
