You have quite a variety of plants that need some help. Spiky one is an agave, too shriveled to ID properly. The silvery one is probably a kalanchoe. The larger reddish one is a Crassula. There's an echeveria in there too.

At the right edge of pic 1, looks like:

Pickle Cactus (Delosperma echinatum)

The silvery one could be Adromischus hemisphaericus.

The reddish Crassula could be perforata.

The one with the smallest foliage could be Sedum album.

Thanks for the help. I am aware they are not doing so well, I'm reading up and changing the way I water them to see if I can save them. I think I have been under watering them. I have quite a few more to ID as well, but I didn't want to post dozens of pictures in my first post.

Happy to suggest.
