Can I rescue leaning concrete forms?
Actually, now that I think about it, I've seen pros pour posts that were worse than that, and it didn't rain!  lol.  Don't think you're in bad shape.  You can certainly use them.  Try packing the downward leaning side hard with a dirt tamp, you just might get that 1/4" back. Don't be afraid to use the pull and grunt method. Brute strength. Being only 30" deep, you may be able to force them back to plumb and compact the voided side with a tamp and some fill.
