1 and 3 are Echeverias, 2 is a Graptopetalum. Might be G. Pentsndrun, I just bought same one and am going to post it here. Echies could be many things, maybe ‘Dondo’... hard to say. The Echies will need a lot if sun, I have to keep them under lights here to get them through winter. The Grapto might be okay in a south facing window..

edit: I now think it might be G. ‘Murasaki’ , a hybrid.

Are these from Kent too?

care for these is similar to most suxx, well draining soil, lots of light and only water when good and dry.

They are from Kent and have generic ‘2.5 inch succulent’ tags, with the proper size obviously haha. I was leaning towards ‘Dondo’ as well for 3. If it helps, looking back at the pictures, 2 is actually more purple on the outside, it just doesn’t show up all that well
