new little succulents

I have 3 different Haworthia's planted in the one pot, the first two which I think are H Fasciata & H attentuata, I took a couple of plantlets from a house my parents were housesitting, they were very old and overgrown, have been in the pot for 1 year now & done nothing!  Today I purchased a H tesselata to go with them, doesnt look much like its picture, looks very grim & almost dead, hopefully being transplanted it will show some life now.  Apparently they are very slow growers, so will take some time to fill this pot.

I also bought what I think looks like an Agave, which one Im not sure, as the only label it came with was "succulent" which of course is no help at all.
The other two photo's are an echeveria black prince & aeonium chocolate rose, all of these I will grow in pots until we move & then they will find their home in my dry succulent garden.
