Luna Lovegood and Cho Chang are kind of the main ones. Other Ravenclaws include Penelope Clearwater (Percy's girlfriend in the early books), Roger Davies (Quidditch captain), Marietta Edgecombe (Cho's friend who sells out the D.A. in the fifth book), Michael Corner (Ginny's boyfriend in the fifth book), and Padma Patil (Parvati's twin sister; she's a Gryffindor in the films, but a Ravenclaw in the books).
They're called Ravenclaw's. They don't have any other nicknames.
