The cactus looks like a Sulcorebutia.

The pineapple leafed plant is a Haworthia. Not sure of the species though.

The long, skinny Haworthia on the right side of your pic might be Haworthia reinwardtii.

Here is a link that might be useful: Haworthia page

I was thinking some kind of Bromeliad for the spikey one-- a Hechtia or Dyckia, something like that.
You did WELL!

The cactus is likely to be Matucana aureiflora, or ritteri... they have very similar appearance, aureiflora has golden flowers, and ritteri has red. I'm with Rosemarie on the Haworthia.

Cheers, CP.

I don't think that one is an agave. I don't see the spine on the ends of the leaves.

Do you think the cactus is that big? It would be a big old thing if it is a Matucana.

I guess I could have helped you all with scale.The majority of the pots are all 1 gallon.The 2 smaller plants are in 4inch pots.Thanks RosemarieRo for the Haworthia reinwardtii id.Thanks Ooojen for the "Hechtia or Dyckia" response.I believe my 1 gal. to be Dyckia brevifolia and the smaller one a Hechtia.I agree with CP on Matucana aureiflora,also 1gal.I do have my eye on a Sulcorebutia, snb and I'll include photos.I must go back to that nursery!!!!

I'm starting to see the size of your kill! A gallon pot should be over 6" across the top, so that is one nice plant :)
