Q: What waist size for the 6xl?

I'm 5'8" and wear a large. I have a kid working for me that is 6'2" and wears a 2XL. Don't know the answer to your question, but maybe this could be helpful.

Q: I’m 5’6 180lbs waste size i wear pants 31-30 what size should I get

Medium size should be a good fit. Might be a little big but will allow you room for clothes that you wear. I weigh around 170lbs and wear a size 33-34 in pants and medium is a good fit for me.
