Thanks guys, this has been super helpful so far. Here are some better pictures of the lighter/mint green one on the right in the picture of the back, as I think it's the only one left that doesn't at least have a genus name. Unfortunately it got damaged during somewhere along the line of to and from the celebration I got it at and what I would say is a good 40% of it's leaves were stripped off of one side, so it's probably a lot rounder in shape (as in circumference) in reality. I believe the smaller ones next to it (pictured last) are the same species, just younger/smaller. Sorry if any of these are blurry, was having trouble getting the phone camera to focus so close up. Also I'm in Ohio if that helps (the person I got them from isn't from out of state). (leaves that were laying in the pot)

It looks more like a Sempervivum to me. Similar form to Echeveria, but these are hardy outdoor succulents. Give it well draining soil and lots of sun and it should do well. It will bloom, but the rosette will die after flowering. However the main plant should produce some offsets before it bloom, so you won't lose everything..

I am using a commercial cactus/succulent mix, but I didn't realize I would need to mix it with more pumice/perlite. I'll try to get my hands on some of that soon and do some repotting. I got the cuttings in the mail (shipped from California to the east coast), so the 'wounds' had time to scab over before I planted them. I put them in the soil and let them sit for a few days. I've watered them twice in the three weeks since I potted them. Some definitely have roots, but some haven't rooted yet.
