Your grandma's brother is your parents' uncle, so he is your great uncle. if he got married and had a son, then your parents now have a cousin.
People with the same grandparents are first cousins. People with the same great grandparents are second cousins. This man is one generation away from you, so he is your second cousin, once removed.
If you have no siblings but your daughter has an uncle, he is the brother of your spouse, your brother-in-law.
1st cousin 2x removed
Your sister's son is her grandson and your great nephew. Some use the term "grand nephew."
