Your father's sister is your aunt and her husband is your uncle. Some would say "uncle by marriage."
The relationship to you would be your cousin !
I cannot see why not. There is no blood relationship between you and your sisters ex-husband.
Let's see if we can unravel this. Your sister's husband's father's brother is your sister's husband's uncle. The uncle's daughter is your sister's husband's cousin. There is no relationship to your sister, unless your sister wants to call her a cousin-in-law. To break it down to its simplest terms: She is your brother-in-law's cousin and no relationship to you.
Brother-in-law
daughter
Your sister's husband is your children's uncle. They are his nieces and nephews.
Your kids and my sister's husband bear no relationship to each other. It is extremely unlikely that they even know each other.

Your sister's husband is your brother in-law, there's no different word in english to describe the husband of an older or younger sister.
