Acrylic craft paints

Yes you can use those Testors paints also but they also need to be thinned and cleaned out of the airbrush with a strong cleaner like lacquer thinner or at least enamel thinner.

Both stink and you need ventilation.

If fumes are a problem in the garage then acrylics would be better for you, but they should not be inhaled either so you need some ventilation or a respirator when you paint.  

Robert,

For acrylics I would recommend Tamiya, Vallejo or one of the other quality paints out there.

If fumes are not a problem the Model Master enamel line is excellent. 

That depends on the paints and the airbrush, but as a general rule a definite maybe!

Properly thinned craft acrylics can be sprayed through most airbrushes, but would probably require a "coarse" needle/tip combination. The pigments used in those paints tend to be rather large.
