I think it's pretty unanimous that aura is different depending on each person and their personality. The topic of it manifesting is likely connected. I believe aura is what gives the characters their speed and strength. I think that any time a person is doing something that should be impossible, they are using their aura to augment physical capabilities. Surviving powerful blows is just one ability of aura. Ruby's flash step speed would also require use of her aura, and is why rose petals appeared when she did so. Yang's fire was also a manifestation as she used more aura to increase the strength of her attacks. I think that Jaune and Pyrrha glowing was a side effect of her using her aura to unlock his. Also, the rose petals when Ruby kills a grimm is due to their weapons being a channel for their aura, as Pyrrha said.
