Yes, one on left is Haworthia attenuata.
Middle, yes a Senecio, S. ferreyrae.
On the right, could be an intergeneric, with Graptopetalum in the mix.

As for your sideways photo, some programs turn them upright automatically for you to view. Did you, by chance, take this pic with your cell phone? (Because if I view on my cell phone, the pic is upright. On my laptop~sideways.) Seems to happen a lot on the forum these days.

You are awesome! Thanks!
Yes, this was taken on a cell. I uploaded from a laptop, and then noticed all of the sideways pictures. So I opened everything in photoshpop & made sure they were upright before renaming.
