my advice would be get a set of stock rims, whatever, can be had cheap (100-200) sometimes including tyres too - of course depending on condition, but could last you until you save up for whatever you want.
but yeah you could just fix them up and run them again. but i think, having read AND talked to other wheel repairers (i had buckles worse than these), even if you fix them they will never be the same structural integrity again AND not to mention, do you know if the buckle goes all the way to the other side? Something that bad usually buckles the entire rim...if you stick it on a wheel balancer you'll see. Thought it's obviously bad enough to not hold air so...yeah
