Answer

Hi,
Here’s a quick breakdown:
	1.	Someone married once. → OK, but sounds incomplete. Better as “Someone got married once.”
	2.	If I could go back, I would never marry. → OK, means you would avoid marriage in general.
	3.	If I could go back, I would never have married. → Correct and more natural; refers to a specific past marriage.
	4.	Someone married again. → OK, but more natural as “Someone got married again.”
