That we know off. Only from number 1 to 4 were Vasto Lordes. From 5 to 8 they were Adjuchas, and number 9 we know he was a Gillian.

Has for Yammy. He didn't seemed like a Vasto Lord to me. None of his resurrección two forms were anything like a Vasto Lord is supposed to look like. Maybe just like number 9 that had a special ability that allowed him even being a Gillain to stand amongst the Espadas, so to Yammy might have been a Gillian or a Adjucha with a special ability to made him the most powerful of all of them.

So Starrk, Barragan, Harribel and Ulquiorra.
