None of them are stated, really, but if you do the math, some of them are known, like Joseph, who is for all I know, stated on his grave, jotaro is known to be 17 during the stardust crusade, and the crusade takes place in the mid to late 80s. Josuke is 19 during the yoshikage kira investigation, giorno as I know, isn't known. Jonathan is known - ish, we know he's a baby in like, 1880, but he could have been born the year before.
