The top left could be Adromischus maculatus and middle right might be Haworthia ratusa or possibly H. cooperi.
Bottom right could be a Pachyveria of some sort

Thanks for that - much appreciated. I'm really curious actually about middle left - it's a cute little pom pom..I'm wondering how big it gets.

Upper, left (purple) Gasteria species
Right of that, a Senecio
middle, left ~may be Echeveria minima
middle, right ~ Haworthia cymbiformis
bottom, left ~ Oscularia deltoides
Bottom, right ~can't think of at the moment (are there any hairs on it?)

Thanks so much!! The bottom right is pretty hairless

Thanks for checking. Bottom right, looks like it has an inflorescence. Is it in bud? Is there an open bloom or? Might be helpful to see it.
