Two:
1. Male Vanguard, Ruthless Colonist, mostly renegade. Got with Ashley, then left her for Tali (who he always liked in the first game anyway). Kaidan died, Wrex lives, Rachni Queen lives, the Council sacrificed. All ME2 crew members live, the base handed to Cerberus.
2. Female Infiltrator, War Hero Earthborn, mostly paragon. Almost got with Kaidan but then he died at Virmire. Wrex lives, Rachni Queen lives, the Council saved. Haven't played ME2 with her yet so her future choices are yet to be made.
Also I created a male soldier in ME1, planning to be full renegade, but haven't played him past the initial section.
