They got a discount...?

Could be but second guy's answer was what it was suposed to be

everyone is someone's son.

A grandfather, a husband, a father, a son, a brother, a cousin went out to eat. It only cost $5 total.

One of them did not eat.

Yes.
He should have written it:
"Two fathers along with their two sons..."
or
"Two fathers with one son respectively..."
...or something.

A grandfather, a dad and a son went to eat.

The grandfather is a father of the dad and the dad is a father of the son. Two fathers.

The dad is a son of the grandfather and he, the dad has a son. Two sons.
