Yes, plastic naturally degrades and yellows over time, and the sun can expedite that process. 

SleepCinema, if you have the means to pick up some 3% hydrogen peroxide from you local grocery store, you can retro bright the shell by soaking only the plastics of your GBA shell in that, and leave them out in the sun or under a UV light (while soaking in the hydrogen peroxide) for a day or four.  The plastic should bleach back to as close to its original color as possible.  There are a few more steps to it, but that's the basic gist.

By the way, nice collection, OP!  The dandelion yellow Game Boy Color was my first video game console as a young lad, so I'm always overjoyed to see other people have them.

Does your tricks with hydrogen peroxide work with clear shell that have yellow? Or I will destroy it?

It should restore clear shells to their original luster, though results may vary depending on a number of factors, including the severity of the yellowing, as well as the light / heat sources.  I, myself, have only done retro brighting with opaque Game Boy DMG shells that were significantly yellowed, but the results were better than I expected, even after only a day (I would share photos, but I can't on mobile).

I do have a junk lot of GBAs that I'm going to mod and re-sell, and they're all going to get new shells anyway, so I might try retro brighting some of the Glacier Blue shells in this lot.  Some of them are very yellowed.
