They would be in a biological sense. The Joestar Family is rather weird in that the uncles are younger than their nephews, for example Josuke and Jotaro which is noted as being strange in-universe; one can only imagine Joseph's reaction to finding out his uncles consist of DIO's bastards, especially since at least one of them is Japanese.
