They should absolutely be able to support themselves. If they're just leaning but not stretching too much, try rotating them. They'll lean back the other way towards the sun. Rotate them a quarter turn on a regular basis and they will grow straighter.

If they're stretching (etiolating) because they don't have enough light then they may indeed be too weak to support themselves, and supports aren't going to solve anything. You'll have to behead them :) and if the light issue isn't corrected, it'll cycle all over again.

Can you share a photo? You'll get better, more specific advice once we can see the plant in question.

I took away what I had them leaning on for support. The pedals are healthy for the most part, I think, just can't stay up..

Wow.. I had no idea.. I'm getting the things to repot them today. About how far down should I cut it off? And is there a special way to get them more light? I've put them in the spot that they gets the most in the apartment but obviously it's not enough.

Bumping your post to the top so that hopefully those that grow these can give specific advise.

Well I don't know about the two at the front, but the one furthest back looks a lot like one of mine. It's an Echeveria but I don't know/remember which one specifically, here's what mine looks like.

I don't have any additional advice to add really past what greenclaws offered. I would spend some time reading up about Echeveria, either here or elsewhere online to understand how to care for this one at least. Hopefully someone else will recognize the other two and can offer suggestions for those ones.

It looks like one that I have, too. See the lower right of the picture below. To my inexperienced eye, I believe that is an E. Perle Von Nurenberg. I may be wrong and probably butchered the spelling.

I believe it is E. Perle von Nurnberg as Tyler said; it is very similar to E. gibbiflora 'Metallica' - easy to confuse these two:

I use a growlight since I don't get strong enough light for my plants where I live. Of course you would get something smaller if you aren't planning to have such a huge collection like me, but they really do work! My plants are much happier in it than the windowsill they were in before.

Thank you, everyone, for your input. I've gotten things going with the what I believe now to be the proper soil, pot, and amount of light. Things are good so far and hopefully, the basic info will do enough to be able to get them to grow properly so I can finally identify the other two.
