I recently moved from WI to SD, and I have a few young succulents that I inherited from my parents. My mother bought these at our local Farmer's Market from a woman who grows and sells tons and tons of these cute babies. Unfortunately, I don't know what any of them are or how to better care for them. I think one or two of them might be sick, but I don't know why or how to help them. :'(

I did re-pot all of them in a better soil about two weeks ago (they were all in plain indoor potting soil, and I think they had gotten too much water before I inherited them), but I think I might have taken too long. I didn't know the soil was bad until a few weeks after I got here and I think I might have blundered by trying to let the soil dry a bit before I decided to scrap it and re-pot. None of them had any visibly dark or rotting roots at the time but I've been afraid to lift them to check. I have only watered them once since re-potting, aside from one light misting.

I also drove here and the poor darlings had to sit in my car overnight when the temp went down to about 38 degrees F because the hotel wouldn't let me take them in to my room. I had them in a cardboard box lined and insulated with warm clothes and covered with my insulated winter coat (I had it propped up slightly in the middle so it didn't crush any of them), but it might not have been enough to keep them safe.

Here's plant #1:

I'm worried about all of those brown spots. It didn't have them when I got it and I don't know what they are. The only other thing I can say is that the new growth coming from the side sprouted up at the same time, but it also has those sad brown spots on it. :(

For what it's worth, whatever it does have doesn't seem to be contagious. None of the other plants have gotten them.

Here's #2:

I'm really confused about this one too. The inner "leaves" keep falling off, almost crumbling off, but it's growing new roots like crazy. I'm not sure if the inner growth is yellow because it's dry or because it's not getting enough light, or... well, whatever else it could be? It does seem happier since being re-potted, but I'm worried about it all the same.

Plant #3:

This one seems okay? It does have a few patches that are lighter/not as green, as the photos show.

#4:

This one perked up a LOT after re-potting. It was nearly flat and it looked almost grayish in tone. It's gotten much greener, but the bottom leaves still look brownish-grayish, and one of them is a little shriveled at the tip. I feel like it used to have quite a bit of red color and now is only green... but I can't be sure, since I've only had it for a few weeks, and it barely had any color when I got it.

And finally, plant #5:

This one, I think is aeonium arboreum (or "Irish rose") but I'd like a confirmation. This baby has gotten sooo green, but I think it's still reaching pretty desperately for light. When I first got it, it looked like a tree out of a Dr. Seuss book! It's grown quite a bit in the short time I've had it.

We have very limited sunlight here, as we're in the mountains. It's only light out for a few hours a day, and our apartment windows (which face South) are probably far too cold to keep the plants by. I currently have them under a 100w-equivalent CFL (5000k) in a fairly open room. I think the air flow is pretty decent.

Any IDs or advice would be enormously appreciated! Especially anything that might be doable on a limited income...
