Either your son or your nephew is the man.Your father's son is either you or your brother (including half-brother).If your father's son is you, then the original man is your son, (you are his father).If your father's son is your brother, then the original man is your nephew, (your brother is his father).Obviously if you have no brothers, than it must be your son.
A son of your father's brother would be your cousin.
Your father's brother's son is your first cousin.
The son of your half-brother's father is not related to you when the father is not your father.
Your father's brother's son is your first cousin.
It's you. You are the son of your father, but you are not your own brother.

To your father 'Brother', to your father's father 'Son', to you 'Uncle'.
