Answer 1

Explanation:

Your father's cousin's daughter is your second cousin. She is technically your father's first cousin once removed. (Your family most likely calls them each other's “uncle” and “niece” because, well, it's easier, and/or your dad and his cousin have a very close relationship, more like brothers than cousins.)

Answer 2

It is basically termed as second cousin. In simple words you call it uncle.
