Just a few questions, eh?
You'll want to test the paint first; it may be compatible, it might not be. Dab a bit on an inconspicuous place and see.
As far as using it in the airbrush, it should work, provided you thin it enough. Use an appropriate thinner (recommended by the manufacturer). The paint should be the consistency of 2% milk, or just slightly thicker than water, which is a lot of thinning for house paint.
Smooth lines between paint colors is accomplished by properly masking your model with tape. MR has a couple of good videos on how to do this, and there are probably a lot on YouTube.
You might want to consider mixing your own colors from acrylics or enamels rather than letting the paint color steer you into a specific type of paint. I have been using exclusively acrylic paints for years now (mostly Testors' ModelMaster Acryl and Polly Scale). I have about 60 different colors in bottles, plus about 2 dozen bottles of colors that I've mixed myself. I use a pipette and write down the mixture so that I can reproduce it.

I would steer away from Latex paint. It's not intented for use with plastics. Latex also tends to be a bit lumpy even when thinned and would have to be strained before use. Latex paints aren't designed to be thinned as much as is need for airbrushing.
There are water based acrylic model paints that you can find at most hobby shops, these are designed to stck to plastics: ModelMaster Acrylic, Polyscale, Modelflex. All three have several dozens of colors, the last 2 are mostly railroad colors. Google them for color charts.
Another source for water based acrylics are acrylic craft paints sold by Walmart and craftstores, a couple of brands are Apple Barrel and Creamcoat. They are thicker than the model paints but can be thinned with water (distilled water is recommended - you can get it in grocery stores by the jug).
Regardless of the type/brand of paint used, for airbrushing, it needs to be thinned to the consistency of 2% milk, using a medium/No.3 tip @ 18 - 25 psi (pounds per square inch air pressure) at a distance from the object of about 6 inches.

not a good idea.it is latex paint not for airbrushes no matter how much it it diluted. that is my opionrambo1...
look it might also ruing the brush. don't try it rambo1..
I use latex house paint in an old Testor's Aztec external mix airbrush, but I thin it first then filter it through a paper towel to get the chunks out. I also removed the thin suction tube from the airbrush bottle cap and replaced it with part of the bulb end of a pipette. It's not great for detail painting but it covers large areas well with a thin coat. I wouldn't dream of using it with an internal mix airbrush.
