No, he married Eva Braun, who was not his cousin.
Your mother's(mum) nephew is your cousin. His daughter is your cousin once removed; as she is in one generation below your own. When/if you have children of your own, she will be their second cousin, as she is the same generation as your children.

Me and my cousin
No, you are related like it or not. But, once you are grown, you don't have to associate with your cousin if you don't want to.
Your mother's sister's daughter is your first cousin. That cousin's father's brother's son is her cousin. There is no relationship between you and this cousin's cousin unless there is another family connection.Your first cousin, once removed, could be either your first cousin's child or your parent's first cousin.
Step son or not regarding your mother's cousin that would make him your third cousin.
Make eyes at his brother...
No, because there is not relationship called "cousin-in-law."
No, you would only be an aunt if a sister had a baby. If your cousin had a baby then the baby would be your second cousin.
