Numero Uno mystery is Linda Christian who was, for a time, Mrs. Tyrone Power. She was also, for a time, married to this gentlemen, featured here inside mitten drinnen. Seems she & Ed (shown here) were offered the leads in "From Here To Eternity", but Linda wasn't in the mood to make the picture. Oh well.
Ronny Coleman was gussied up to play Hafiz in "Kismet" opposite Dietrich, who is not the other mystery in my snapshot.
Number three is Jesse White, probably most famous as the long suffering Maytag repairman. My shot may be from "Harvey", (1950) where he played Wilson, sanitarium orderly, his first credited film role.
