The English language does not have a specific term for the wife of your nephew. If referring to her other than by name, you would simply call her "my nephew's wife" or, if you want to be more distant, "my great nephew's mother."
It is quite normal to describe her as your niece. All of the foregoing answer is simply pussyfooting.
Yes.
The English language has no relationship name for the wife of your great niece or great nephew.
Your nephew's first cousin may or may not be related to you, depending on how the cousin is related to your nephew. Your nephew's cousin may be your child, or the child of one of your brothers or sisters. Your nephew is related to you by being the son of your sibling. That sibling has a spouse who may also have borthers and sisters. The children of any of those brothers and sisters are also your nephew's first cousins, but are not related to you.
Your nephew's son isyour great nephew. You are his great aunt or great uncle.
Your grandchildren and your nephew are related t each other as first cousins, once removed.
The nephew of a wife and the nephew of her husband are not considered to be related to each other. However, both are nephews of the wife and the husband, and the wife and husband are aunt and uncle to both nephews.
Your grandson and your nephew are first cousins, once removed.

No
Your grandfather's nephew is your parent's first cousin. Your grandfather's nephew's daughter is your second cousin.
Oh, dude, let me break it down for you. Your half-brother's nephew is technically your half-nephew. I know, mind-blowing stuff, right? So, yeah, you two are related, but like, not super closely or anything.
