I'll give it a shot:
Front row: crassula muscosa, cactus (I'm not very good at identifying cacti), crassula ovata gollum.
Second row: adromischus (not sure of the exact species), cactus?, aloe (also not sure of exact ID)
Third row: Zebra Haworthia, crassula (looks like it could be perforata), cactus?, ??, sempervivum.
It's a little difficult to see the ones in the back, but back right looks like it could be kalanchoe tomentosa.
Hope this helps, and happy collecting!
