If they weren't Queen...here's what my impression of Brian, Roger, Freddie, and John would be, just by the appearance.
Brian: Looks almost like a transsexual. Maybe it's his long hair, but he looks like one of those guys dressing up as a woman.
Roger: Looks exactly as he is, famous or not. He looks like a normal guy.
Freddie: He definitely looks gay, especially when he was younger. One of those artistic hippy types but GAY.
John: The most normal looking guy, and my favorite guy of the band. He just looks like a decent, family oriented man.
