I'm not much help but thats some type of short leafed jade. I have five of those with a really nice red tan. nice aloe that one looks like it's a tree aloe

I think it's a plain old Jade plant -- Crassula ovata. The ordinary Jade (not that there's anything wrong w/ that).

Tree Aloes I've seen tend to be single stems, not multi-stems like the Aloe in this pic.

The aloe is most likely not a tree aloe. Tree aloes, in my experience, tend to grow a full sized rossette before going up. It could be Aloe Maculata/Saponaria. Although aloes are very difficult to identify unless they bloom. And even then, there are so many hybrids that the possibility of a sure id is not big. good luck!
