Answer: Those are her roomates. The first season Sabrina was in college, she moved out of the house that she shared with her aunts and she moved in with 2 girls plus another guy. I think her aunts went back to the other realm since the 2 actresses (Caroline Rhea and Beth Broderick) who played them left the show. The guy roommate also left the show the same time as Sabrina's Aunts. Then Sabrina and her roommates moved into the house.
