can anybody help me identify these plants

I found all of these at my schools greenhouse. They’re all succulents and they’re leaves that fell off the main plant and started growing roots so i just took them lmao. The greenhouse at my school doesn’t have any signs on what the plants are so i’m not sure what most of these are. I think the green and white ones are jade plants but that’s it. The one that i think is a jade plant didn’t have roots growing from it yet so i’m not sure on what I should do for that one. Also does anybody have any advice on how to propagate them? should I just stick them in soil? water? I’m not the greatest at propagating succulents any advice will help!
