Chris, did you get IDs for your plants yet? I think 6143 might be crassula mucosa, watchchain plant Watch Chain Plant (Crassula muscosa)
6140 could be variegated jade, crassula ovata ,Jade Plant (Crassula ovata 'Variegata')
6146 Miniature Pine Tree (Crassula tetragona)
6145 could be an echeveria and the last I would venture to say may be a sedum of some sort or better yet, a kalanchoe. They are both etoliated, so it's hard to say.
Hopefully the real experts could chime in for positive IDs.
