Yes but only because your married to the guy.
She is your sister-in-law.
Your mother's brother is your uncle. Your uncle's brother-in-law is either the husband of his sister or the brother of his wife. The brother of your uncle's wife is not related to you. The husband of your uncle's sister is either your father, or the husband of another one of your mother's sisters and thus your uncle.
I cannot see why not. There is no blood relationship between you and your sisters ex-husband.
Your aunts and uncles are the sisters and brothers of your parents. So they are "blood related." But you also call the husband of your mother's sister your uncle, and he is not "blood related." So aunts and uncles are not always really related to you.
No. Neither is your cousin-in-law, or her sisters. In-laws are not blood relative (i.e., members of your family or lineage) therefore anyone related to an in-law is not a relative.
sister in law
sisters are people who are related
You are related to your husband by marriage. He is your spouse.
