Q: I have a 7 5/8 dome, what size should I order for this hat?

I'm not expert, but you should probably go with m/l

Q: My husband’s Head circumference is 24”, what size hat should I buy him?

XL is 7 3/4 which would be 24 1/4" typically

Q: What size should I get, my head measures 21 and 5/8 inches ?

Hey Winston, Mate I work in metric and my head is 54cm, according to my tape measure that is 21 1/4 inch and I got the Extra small and I put a piece of material half way round the inside of the brim. I had trouble with a local purchase of this hat being too big so I would recommend going the smaller size than the size that they advertise. Hope this helps mate, Cheers Simon (Australia)
