Your wife's brother is your brother-in-law.
He is your Brother-in-law
Brother-in-law
You are your brother's wife's brother-in-law, if you are male. But your brother's wife can also have brothers-in-law who are not related to you or to your brother. They would be the husband's of the wife's sisters.
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.
The relative of someone who is married into your family is never of any relation to you. So you sister's husband's cousin is not related to you in any way. Which, of course, is not to say that they can't feellike family.
Your sister-in-law's husband may be your brother. If so then the brother-in-law is either your husband, in which case the daughter is your daughter; or the brother-in-law is your brother, so the daughter is your niece or the brother-in-law is the brother of another sibling's spouse, in which case the daughter is still your niece If your sister-in-law's husband is not your brother, then he is not related to you and his brother-in-law's daughter is not related to you.
Brother-in-law.

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.
I cannot see why not. There is no blood relationship between you and your sisters ex-husband.
Your sister's husband is your brother-in-law.
Nothing, your husband's brother is your brother in law but his wife isnt related
