Let's just say i want to recharge a rechargeable battery with another AA battery...

(I know it wouldn't work very well but lets just say that it does) does the positive part of the regular battery go to the positive part of the rechargeable battery? I am trying to recharge a battery and i don't want to ruin the rechargeable battery so i just wanted to make sure that i was going in the right direction...

Positive to positive, negative to negative. You are trying to force the chemical reaction backwards. I think that there's an instructable using a joule thief to do this : )
