Your uncle. Assuming your aunt is a sibling of one of your parents, your uncle would be defined as whoever happens to be married to her. You're welcome to continue calling the first husband your uncle if you feel it's appropriate.
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.
the daughter's cousin
She's technically your aunt-in-law. You obviously wouldn't actually call her "Aunt in law Sally", so you should just refer to her as "Aunt Sally."
Aunts.
They'd be your cousin.
Your grandmother's sisters are your Great Aunts.
