I can tell you without any ID that they need well draining potting mix (not the peaty soil they usually come from the store in); container with drainage holes (1 & 2 seems to be plastic pots so I am almost sure they have them). Last pic shows glass tumbler or something - is there drainage hole? If not, it should be repotted asap. And they all will need lots of good light - transitioning them slowly if they were in low light spot to prevent burning...

While they're all Echeverias, their individuals IDs don't matter as they'll all take the same care.

Rina is correct above suggesting that far more important than IDying them for their care, is correcting bad soils & bad pots they're in so they'll have a chance to do well, not just survive.

Agreeing with Rina. All Echeverias. Two is a Black Prince, three is what I believe to be a Pulidonis just since you want to know. Pretty plants, but if you don't do something about their mix and pots they won't be for much longer.

#1 could be E. shaviana or E. 'Neon breakers' (that is a hybrid of shaviana...so they look quite similar).
