I have a 2013 honda civic?

I was wondering if I can buy the 16" rims that came with the higher model civics to replace my regular cabs?

Yea should be no problem. Just double check the bolt pattern.

I'm guessing you got the LX trim? If so it shouldn't be a problem swapping them with the 16 inch Honda rims only thing you'll probably have to buy new tires too.

Absolutely. As long as the larger rims have the proper bolt pattern, offset and backspacing.
