The mixed arrangement looks like you've got a lot of echeverias. The dark plant that is hard to see in the front looks like an aloe. The tall plant is probably a Madagascar Palm. The fuzzy plants might be echeveria setosa. A better pic would help in an accurate id :)

1. Eheveria - harmsii or pulvinata or Doris Talor 2. Sempervivum - best if grown outdoors 3. grafted cacti (yellow), don't be surprised in case it dies, the pure yellow (or red, or pink) can't survive on their own; in case it dies the lower part (the stock plant) usually keeps growing

With the more narrow width of the leaves of the plant in question, it is not Kalanchoe/Bryophyllum daigremontiana but a hybrid thereof (with K. delagoensis): K./B. x houghtonii.

You're so right! I feel like a dummy about the Frosty, because I see its crested form all over the place...guess I'd just never seen the normal kind before. But that's totally it. I'm almost positive you're correct about the cactus, too. Thanks for your help!
