Port was a TA while STRQ were students at Beacon.

Generally speaking a TA is themself a student; as it is a form of on the job training for those looking to become teachers. He's more likely the same age as Oobleck.

As for Ozpin; he was apparently the youngest headmaster ever assigned to an Academy; and his tenure was unknown. For all we know he was only in his 50s.

Edward Caspian from After The Fall is where the information that 70 is abnormally old for a Huntsman came from.
