Bromelia,

So many hybrids, without DNA testing it is sometimes impossible, eh? And particularly when they are young plants with no flowers.

The one on the right, maybe some Sedum and Graptopetalum, the one on the left, it looks like Echeveria and something else. I do not know these plantas but I would grow them too.

The left looks like Sedum palmeri. If yellow flowers, post pix again to confirm. The 2nd may be Sedum or intergeneric, like a Sedeveria.
