Your uncle's wife's brother's son shares no ancestors with you and so is not related to you - unless the brother is married to one of your cousins.

His great uncle

Your mother's brother is your uncle.The children of your aunts and uncles are your first cousins.
Great uncle / Great nephew
your second cousin- in law or by her name lol
Your uncle's son is your first cousin.
Yes. Any son or daughter of Zeus would be her half-sibling. Any son or daughter of Poseidon or Hades would be her cousin as Poseidon and Hades are her uncles.
It means you have (or had) at least two uncles and at least two great-uncles, and that is all it means.
No because that would be your cousin
Your grandmother's sister is your great aunt, her grand children are your second cousins twice removed. Genetically speaking this is barely a relationship - but if you were raised together as cousins the familiar bond can be tight.
