1. I believe that's everyone. I'm assuming you didn't mention Necola since she's probably in her human form for you.
2. Depending on the animations, it could be bugged. But you're probably talking about the 0.4.X animations. Those haven't been updated to the gallery yet and will come a bit later.
3. The yellow money is yours and the red one is Tori's. Tori can gain money during hunts and you can use it to by items.
4. As far as I know, there's no way to see the quests you have available or pending. I've been occasionally asking the dev to make sure I've done everything in the 0.4.X update. Usually the gallery helps with figuring out whether or not you've completed everything, but that hasn't been updated yet.
