The two women on the bottom are lesbian girlfriends, Georgia's the one in the purple jacket and Tina's the one in the green shirt. On the top there's a little boy named Andy (who's the adopted son of both Georgia and Tina,) and the roommate they had since college, Rachael, the one in the gray jacket.
Edwina's the one in the navy blue varsity shirt, Ida's the one in the white and green dress and little bow. The two at the bottom is Preston (The boy with dog ears and wearing a lighter blue varsity shirt,) and Tobar the lepherquin (Some species I made up.) Their appearances in the comic are coming soon though.
