We use Great Aunt with our children "Great Aunt Cathy".

If your great-niece has a baby, that baby would be your great-great-niece or great-great-nephew. This relationship is one generation further down from your great-niece, making you the great-great-relative. Essentially, you would be the great-great-aunt or great-great-uncle to the child.
Your nephew's daughter is your great niece. Her child is your great great niece or great great nephew.

Your sister's aunt (who is also your aunt) is the baby's great aunt. The baby is a great niece or great nephew of your sister's aunt.
Oh, dude, if my niece has a baby, I'm technically the baby's great uncle. Like, I know, right? It's like being an uncle, but with a little extra "great" thrown in there. So, yeah, I'd be the great uncle, but let's be real, I'm just gonna be the cool uncle who spoils the kid with candy and bad jokes.
That's easy cousins.
You are great great aunt to your niece's grandchild. Your children and your niece's grandchild are first cousins, twice removed.
The child of your nephew is your great nephew (if a son) or your great niece (if a daughter).
