A brother and a sister, both being children of the same parents, are siblings.
They are Brother & Sister.
Your sister-in-law is either the wife of your brother or the sister of your spouse. If you have more than one brother, and your sister-in-law is the wife of one brother, then she is the sister-in-law of the other. If your sister-in-law is the sister of your spouse, she has no direct relationship to your brother. He can call her "my brother's sister-in-law", or "my nephew's aunt."
Your sister's daughter and your sister's brother are niece and uncle to each other. The daughter is the niece of the brother and the brother is uncle to the daughter.
Your sister's husband is your brother-in-law. Your brother-in-law's brother is not related to you and neither are his children. But he is your sister's brother-in-law and his children are your sister's nieces and nephews.
Your brother's son is your nephew, but the English language has no term for a relationship between you and the wife of your nephew. If you have to refer to her other than by name, the best you can do is call her "my nephew's wife" or "my brother's daughter-in-law."
Your brother's wife is your sister-in-law. The English language has no relationship term for the brother of your sister-in-law. He is not considered to be related toyou, although he is your brother's brother-in-law.
