Pyrrha explained that everyone has Aura, but she also says that you need practice in order to use it. Then goes on to explain how it is an extension of oneself and all that other stuff. You can clearly see Ren using his Aura to fight against the snakes, but Weiss on the other hand seems to only be using Dust instead because that is the source of power. I'm not saying characters can't use these things, but that they seem to use more of one then the other. Ren in his fight focuses on Aura to help him fight, Weiss uses Dust, and Ruby relies more on her scythe and bullets.
