If so, yes they are all independent from each other in every way (unlike a rack)
I would suggest AP over boaphile. Boaphile has terrible customer service, and their cages aren't made as well as AP cages are (AP cages are made from plastic that is twice as thick as boaphiles are. Plus if you order a T8 from AP (the cage I would recommend for BP's and most snakes of similar size you will get your cage in about 10 days vs 6-8 weeks for the boaphile.
Yes, single cages, but stacked on top of each other like you'd see in a store. That's really good to know about the wait times, I'm not what you'd call a "patient" person, so that kind of wait would drive me nuts.
