In your bottom pick, the plant on the left is a type of snake plant, the two on the right are ZZ plants I believe. Hope this helps :)

Plants in white container (photo before the last) look like bromeliads to me - not really familiar with them, but look up Earth star (or post on Bromeliads forum for ID).

Jades have smaller and thicker leaves - I also think 2 plants in last photo could be a ZZ plant.

Help in ID with the cacti would be very much appreciated.

I think #2 is Mammilleria plumosa if it blooms white. 2-3 are mammillerias.

I find this link helpful in searching out ID's on cactus. There are millions of mammallerias but this is a good place to start off.

Here is there Mammillaria page. There are some other sites out there that are more complete.

Sorry I don't know cacti, so I'll speak to the rest.

I think Rina's correct suggesting the oblong dish contains Bromeliads, she said Earth Stars, I believe that Latin name would be Cryptanthus, I think they're considered tropicals.

As already IDed, the last pic shows a Snake plant (Sansevieria) & 2 ZZ plants (Zamiocalcus zamifolia). The last pix's soil looks very peaty, not good for any of the 3 plants in the last pic (all 3 are succulents). Also the pot for the Sans, is too large for that plant (unless it has LARGE roots). Overly large pots & peaty soil often combine to cause root rot when overwatered. If you can't get better mix, pls. try to get perlite & then mix it 50/50 w/ that soil. Wait a few days after repotting & then water well 'til water comes out the bottom.

I grow several pots of ZZ plants & suspect that yellowing could be a root rot problem. If it were mine, I'd turn it out to check the roots for rot. ZZ plants also have a tuber, like a small potato: sometimes w/ roots, sometimes instead of roots. if you find something like that, it's normal, so pls. don't toss it.

I'd avoid those white topdressing stones until you learn these plants & their watering needs.

Good luck!
