Is it possible for one to be the reincarnation of real people. For instance, Bonaparte or the Red Baron etc. or must the previous souls all be fictional? Can one be the reincarnation of a completely fictional previous character they created in another RP?

Yes, and I suggest that you research for the most badass people possible. Jan Sobieski of the 1683 war is one of my favorites.
