is is bad for the car if one of my rear tires has 70% tread and the other rear tire has no tread left?

I think that is normal if you don't have a LSD.

well i have one tire with like 5% thread left and i got a flat tire on the other so i am riding around on my spare i was thinking of buying a used tire and putting it on for a month until it is cold enough to put my winter tires on. would it be a bad idea?

Spare tires are not meant to be used for such a long period of time.

i know, thats why i want to get a tire to put on my rim for now. I just dont know if it is okay to have one tire almost completely bald and another that is virtually new

Just put the winter tires on now...

if you only have 5% left on one side while the other one is flat just change both. Don't get 1 side 70% and other side 5%...I'm not sure how the "drive" will be and how the car will handle but I'm sure there will be some implications.

im probably going to get two new rear tires and wear them out in 3 weeks before my winter tires come on what would happen if i got 255/40/18's? because i know stock is 255/35/18. is this not recommended?

its 65 degrees here, i wouldnt want to wear my winter tires out before winter is even here...

Just replace the tire with no tread remaining and continue with the tire with 70% tread left on the other side. Chances are the new tire will wear out at a quicker rate than the 70% tread one again, possibly due to driving style and pattern, which means you'll quite likely end up having both tires ready to be replaced at the same time next time you need to get new tires.

PS: It's tire tread, not wheel tread. Cheers.
