So there are some who I can recognize in the following, but the rest I can't figure out. Have they been intro'ed and if so who are they?

There were others, too, that she didn't recognize - a short
woman in a Wedge Defense Force dress uniform, a tall man with craggy
Nordic looks and a great sheaf of blond hair, a bearded, redheaded man
in a windbreaker, a rotund gentleman whose tuxedo made him look rather
like a benevolent Weeble, and a tall, slim black woman in a scarlet
dress.

They're mentioned down in the credits.
