I don't know if they are real or not, but you have to look at the casting "type". For example, with the men.
#1 The Rebel (Scott from BB4)
#2 The older guy that has to try to fit in (Jack BB4)
#3 Don't know where he fits in
#4 Same, don't know
#5 Does he look like Nate from BB4 or what?
#6 The looks like a hot shot (Dave from BB4)
I look at them as they fit into a casting type, so I would say, yes, this alsmot as to be it!
