I have had to handle 2 boas at once and it is a major handful. I wouldn't do it except out of necessity. But to answer your question, when I've had company over to play with the snakes, I've had multiples out at the same time with no issues between the snakes. I wouldn't exactly call them "social" but they aren't aggressive toward each other either. Keep in mind that stupid stuff can happen and snakes have been known to bite and/or try to eat each other. That is the biggest reason why I don't handle more than one at the same time unless I absolutely have to.
