Going by these:
Jack Diamond is a hybrid/distorted archetype (Noir Detective/Superhero/Occult Investigator)
Kelly/Sparrow ... not sure what she is. Was the result of a challenge, initially (don't remember the actual challenge itself, but the whole "waking up as a female version of himself" thing was the result of it), and decades of doing "superhero stuff" (earliest attempts at writing were superhero stories... mostly silly ones but still)
The crew from the Between Worlds series are all amalgams of several of these. David is probably pretty much an idealized me, Malcolm is entirely the first type (a mix of several people I know with a wild power tossed into the mix), Thellissandra is an attempt to totally subvert the "mysterious warrior" archetype, Carol ... wound up different from what I'd first planned and I'm not really sure where she wound up. Same with Liz (who started out as "what if my wife were a black haired lesbian, and, essentially, 'Sir Not Appearing in this Film"? and wound up mutating into something wildly different)... and the next generation is something else altogether.
Dane Coleman is ... different. Kind of a mix of all four, nearly evenly.
Nathan/Indigo is, pretty much, Martian Manhunter from DC Comics with a different paint job and personality, and minus the psychic stuff. So I guess that's type 1.
