That looks like Haworthia, not Aloe: note the transparent skin on the top of the leaves which forms 'windows'. I think it is Haworthis venosa, but that is just a SWAG. Put them in a really, really free draining soil mix. For example, take 1 part potting soil and mix it with one part pea-sized gravel. Set the starts basically on top of the soil, and put it in a warm, bright spot. Don't give them a drop of water until you are *sure* you see new, active growth. That could very well take months! Once you see new, active growth, gradually provide as much direct sun as you can, and start a regular succulent plant watering regiment. Seriously, don't water it until you see new growth!

Juan Np, I asked since Sempervivums do not care for too much heat and too much humidity (few other succulents don't). They will grow, but in your hot climate, I would make sure they are not in the hottest sun (usually around noon). Otherwise, they like good light. I have many, but I am in colder zone - my semps grow very well in full sun. They should not be so 'tall' - that seems to be etiolation, maybe it was kept in quite dark spot in the store. It is ok in ground or container. Just make sure there is no water pooling too much around - but you likely know that since you grow other succulents. In ground, I like to plant them on a mound, so they drain. They will grow in very little soil, you'll find them growing over the rocks. They should not have recurving leaves, better light and less water will help. Here is different looking one, Sempervivum 'Oddity' I just got this spring, growing in the container: Here is semp with similar leaves to yours; you can see it is very low to ground and has e number of 'chicks'. The leaves/rosette should not be curving down: They are also monocarpic plants - ones the rosette blooms, it dies. In the meantime, it should produce many offsets (that's why the common name Hens&chicks), that can be left as they grow or separated and planted elsewhere. Hope I am not telling you what you already know :) Your Crassula ovata and portulacaria look very nice, growing them outdoors in good sun makes a difference.

I agree with frank :)

Yes it is.
