If a group of monsters were, say, Slowed and then subjected to Sickening radiance would their speed be one-half normal, or one-fourth?

Slow has, in part:

An affected target’s speed is halved...

A monster who fails their Sickening radiance saving throw:

...suffers one level of exhaustion...

...which will halve its speed when the second level of exhaustion is reached.

Effects don't stack with themselves, but I'm unclear if the halving of speed is the effect, or if different sources of speed halving will apply together.

Yes

From the rules:

Combining Magical Effects

The effects of different spells add together while the durations of those spells overlap. The effects of the same spell cast multiple times don’t combine, however. Instead, the most potent effect—such as the highest bonus—from those castings applies while their durations overlap.

For example, if two clerics cast bless on the same target, that character gains the spell’s benefit only once; he or she doesn’t get to roll two bonus dice.

Any effects from different sources stack. The only exception is when the rules state otherwise (generally when there is no stacking to be done). For example, multiple effects causing advantage or disadvantage won't stack.
