Are these female singers soprano, mezzo soprano or alto?

I'm leaning towards mezzo for a quick answer. Soprano is able to hit the high notes comfortably. Mezzo is a husky soprano vs. alto which is deep for a woman. My final anwer is alto for all 'cept Swift, Clarkson and totally unfamiliar with Lovato. Have lotsa fun with Avril and Michelle cause I can sing along comfortably without having to tune up the voice or worry 'bout damaging it like I did singing with Diana Ross. Then again with today's technology in the studio, U can be anything U want :o)
