DaisyI said:First things first. Make them healthy and happy and then decide to propagate them.
1. Did it used to have a crown of brightly colored flowers? Look at kalanchoe blossfeldiana
2. Variegated Jade Plant (Crassula ovata 'Variegata' )
3. Actually, there are 4 plants in this pot. At 2 0'clock is a Watch Chain Plant (Crassula muscosa). After that, I'm not sure.
4. Does it slime on you when you break a leaf? Have you seen it bloom?
5. Cute but haven't a clue
6. Variegated schefflera (Schefflera arboricola "Variegata")
DaisyI said:#4 Something about the leaves made me think of Pregnant Onions. I think the accepted name is now Albuca bracteata.
Baja_Costero said:The opposite leaves of #1 make me think Cotyledon, especially if that is an inflorescence emerging from the top. It's hard to tell from the photo. If those are flowers coming out the top, they should be pretty good. That's just a guess. The plant should be more compact (and maybe develop red edges on the leaves) in stronger light.
Baja_Costero said:If that's what it is, be aware the plant enjoys a bit of space. You can keep it for a long time in a small pot, but if you give it a bit more room (step by step, one size at a time, as it grows up) you will see it become fuller and branchier. More so than the average succulent. Try to use a fast draining soil for your succulents, like regular potting soil mixed with an equal amount of perlite, pumice, or whatever kind of grit you have available locally, so you can give them space without concerning yourself too much about rot. If you're wanting to reproduce the plant you can easily root the rosette at the end of the stems, and be sure to save the stumps, because they are likely to do this afterwards (forced branching):
