Any gardeners? I picked up some succulents, not really knowing too much about them. By the time I got home I realized they weren't exactly perfect specimens, so I need a little advice before I make any changes.



Photos of them all.

First off, the gardener at the store didn't really know what they were. He gave me names, but when I looked them up later, they were completely different plants. So if they look familiar I would love to know what specific plants they are!

The whiteish blue one is lumpy underneath the leaves. I can't tell if this is normal or a problem. It doesn't feel mushy or anything, just bumpy. The tips are withered a bit too. Barely noticable in the light, but you can see them when it's shady.

The spiky green one has these big white spots and has lost a few leaves. The white spots have a surrounding brown ring, and look like when you burn a hole through paper. Not fuzzy, they are more like holes than bumps. Also looks..crowded? Should I separate them? It looks like there are two main plants, with little plants growing out of them.

Don't know anything about the bulby green one. It looks healthy, but I took pictures in case I'm wrong.

I took them home and tried to care for them for a while like I have read to, but these things aren't going away, so I want to figure out what they are before I mess up.

any advice would help!
