I am going to college and I am only taking one guitar. Which leaves 2 of my guitars at home basically in their cases. I want to know, should i loosen the strings a bit? One is tuned to E standard with 9 gauge strings and the other is tuned to C wich 12 i beleive. They wont be there for years but maybe a few months.

yes slacken the strings, not much just to take the tension off and allows the wood to cope with slight changes in temp or humidity
