yes it's perfectly legal, but it is illegal to marry her.
Alabama has no laws regarding dating. There are laws regarding sexual contact, but that shouldn't be an issue since they are both above 17.
No, it's not legal. It's a felony.

The date grows on the female date palm
There are no laws against dating but it's not allowed for a 21yo to have sex with a 15yo.
If the parents allow it they can date. They can not have sex though until the minor is age of consent.
