1st pic looks like an Aloe. I don't know which. 2nd is a Haworthia....might be a retusa type or turgida (longibracteata could be part of the name)- Hard to say. 3rd might be a Coryphantha echinoidea on the left, perhaps Myrtillocactus geometrizans on the right. 4th is a type of Opuntia & Kalanchoe x kewensis 5th (as stated in another post) Aeonium on the left, Graptopetalum or Sedum in center, Kalanchoe marmorata on right.
As an aside, do your glass bowls (pics 1 & 2) have a drainage hole in the bottom? If no, you'd best transfer the plants to a different container that does have a drainage hole.
