#7 is not a Gillette product, but rather a clone stamped out long after the original patent expired. It could be either a wonderful shave or a bloodthirsty demon.
#9 is a Schick injector Ladies version . . . long pink handle solves that mystery!
#8 looks to be a ball-end Tech handle on an Old Type head. Some guys really like that combination, and years back many "old timers" preferred the Old Type head, buying a Tech just for the handle to replace the commonly cracked Old Type handle.
It looks like you scored well, and have a nice foundation to your collection!
