I think the one on the left, with the narrow leaves is Crassula tetragona. I agree w/ Tarev on the others except the taller one may be a Graptopetalum or one of the bi-generic hybrids like Graptoveria.
The Trandescantia will make a nice hanging house plant. We all had them back in the 70's (with our macrame plant hangers)...
