Your great uncle is your parent's uncle, so the child of your great uncle is your parent's cousin. So you would be their first cousin once removed.
Your father's uncle's uncle is the son of your great great grandfather. He may be your great grandfather or he may be another brother of your great grandfather, and thus your great great uncle.Your father's uncle also has aunts and uncles from the other side of his family. That is, he has uncles who are brothers of that one of his parents who is not a descendant of your great great grandfather. Those uncles are not related to you at all.
Your great grandparents' brothers and sisters are your great great aunts and uncles.
Your great grandparents brothers and sisters are your great uncles and great aunts.
