Please look at my first response to you. There are two ‘hot links’ to two compressors made for airbrushing which I thought might fit the needs of a 13 year old (or anyone who didn’t want to make a major investment in a compressor for airbrushing). Both are reasonably quiet/inexpensive. I used the Harbor Freight one for over three years without problems - I know it works. I have also used my Home Depot ‘Husky’ 3 gal contractor compressor but it is just too loud for MY airbrushing needs - but it works fine. Both the HF and Home Depot are in a similar priced range. If you can afford a more expensive one, Keilau posted a link to the Sparmax Stormforce -a great compressor for airbrushing. My choice would not be the contractor type compressor even though they do work for airbrushing because they are noisy whether from WalMart, Lowes, Home Depot or whatever.
People here are trying to help you - and to help a little more, here’s a link to some youtube videos on Painting Model Aircraft.
I’m sure everyone here hopes that you become a valuable resource for others new to the hobby. As I said earlier, I would like t see you get some tools that make you a happy modeler - I’ve made some recommendations and posted links. If you don’t like them that’s fine too!
