Airbrush paint mixing tips for a beginner?

I am about to use my airbrush for the first time on my Kirk, and am wondering mainly about the paint mixtures. Exactly how much liquid latex do you mix with regular paint, and is thinner always required? I also may need some explanation on how to mix these, as I’m completely new to this. Here’s everything I’m using, I’ll be attempting to use the flesh tone color first.
