Milkmaid's avatar is from a game called Pachinko Sexy Reaction. One of my favorite hentai games on MAME. =^_^=
And the names for Dominion's catgirls are Anna Puna and Uni Puma (Yes, different last names - also, they're androids); the main bad guy's name is Baku or Buaku, depending on how you translate it (He's an android, too, or possibly a cyborg - it's never quite explained); and the fairy-girl's name is Crolis. She's often referred to as Greenpeace, but that's the name of the project that created her, not her name.
