1. yes

2. probably C.o. Crosby's compact

3. probably

Both 1 and 2 are Crassula ovata? What kind/variety/etc. would #1 be?

I did indicate that #2 is most likely Crosby's Compact. That C.o. has smaller leaves. #1 is "common" C.o., that has bigger, green leaves. Leaves will get reddish margins if in good sunlight.

Many succulents will color up somehow in good sunlight. I am saying "common" because it is sold more often than other var.

There are many more var. of Crassula ovata...Tricolor; Hummel's Sunset; Maruba; Akai-Lemon and Lime; and more. There is also Tolkien Group: Hobbit, Gollum...

Other mutations: Convoluta; Coral; Red Coral; Gollum Dwarf'; Ladyfingers; Red Hobbit; Skinny Fingers. I also have what was ID-ed as Horn Tree and another one Giant Horn Tree. Also Undulata, Blue Bird, Rubra.....

There are more names available. Not all are registered/accepted names.
