Were "Rip" Van Kelt's or "Mac" McGivern's first names ever revealed? There's another kid named Rick in their group, thus I don't believe that Van Kelt was ever referred to as Rick. Who were Rip and Mac really?

Not sure about their first names. "Mac" might have been just a nickname for McGivern, we never learn his real first name. In class, all students are addressed by their teachers by title and last name, never by their first name - and, what is weird, it seems that some students are never ever called by their first name even by their peers.
shareRip might have been Ripley.
