cacti and succulent ID.

[tarantulamatt]

hi guys I have been looking for a site that has a active cacti section and I think I may have found it

if anyone can help me ID these I would be very grateful! the first I think could be some sort of mammillaria? I was given this not long ago and isn't in too good of a shape and I thnk over watered, also is the plant on the far right the same species and older or something different?

I don't know the names of them but, the first thing that you need is to change their pots. Plants like those, don't normally like to be in smooth, waterproof containers. Especially not plastic pots. They do much better in unglazed, clay pots.

They would also benefit from a regular, watering plan.

I think the right one is completely different.

I would say the one one the right, in the first pic, is completely different. Can't help you with names, but do a search for succulent id guide, and that site may help you find out what they are.

I think the second on is probably a Opuntia, but there is so much variability in that genus, I'm not sure which species it is.
The third one has leaves that look like a Kalanchoe. Try searching for pictures of Kalanchoe and you should be able to id.
