Yammy didn't seem to have had the brains to be a Vasto Lorde (and the size of him after he uses Resurección is another counterargument). Nnoitra may've been one, but he had a grudge against Nelliel for calling him continuously a beast (among other reasons) and he seemed to hate-kill that colony of Vasto Lordes. In other words, he seems to have been an Adjucha too.

Grimmjow was an Adjuchas before he consumed his five companions, all very powerful Adjuchas. Devouring them might have been enough to turn Grimmjow into a Vasto Lorde; Shawlong and the others were convinced that Grimmjow could become a Vasto Lorde and sacrificed themselves for that very reason. Additionally, there was a clear difference in strength, between Grimmjow and the other five Adjuchas; indicating his greater potential.

Concerning Nnoitra, I never got the impression that he targeted Vasto Lorde specificly, but rather that he relished fighting and killing in general. Despite the difference in power, he remains an Adjucha.
