Beth Buckley and Renee Porter
His roommates in the Whitney Manor apartments. Presumably, they are friends.

Sam's Apartment

 * Emmet Ericson
 * Nigel Giocondo-Jones

Emmet and Nigel both independently decided to break into Sam's apartment via the window. Nigel's attempts to break the lock on the window got them both caught, though Emmet managed to make her way into the apartment. She then immediately revealed herself by knocking over a stack of books. Sam's roommates -- Beth Buckley, Luca Perry, and Renee Porter -- threatened to call the campus police on the duo, so they scurried off.

Trivia

 * Luca is, apparently, a "beefball."
