Aura can appear in different ways depending on a person's personality. While Aura comes from the soul as Pyrrha says, if you have ever seen Soul Eater, a soul can look and act very different depending on the person. This could result in Aura manifesting in different ways.

Yang for example seems to get an adrenaline rush, her eyes turn red, and her hair glows. The flames however are a result of her firing her gauntlets when she goes into this state. Lie Ren is able to make barriers with his Aura and possibly increase his strength. Jaune used his to heal from a cut, but neither Pyrrha or Jaune have shown any kind of Aura skills in battle.

Ruby's rose petals are hard to define, as they don't seem to appear the same way Aura does for the others. I mean they appear almost any time Ruby's cape is blowing in the wind, so maybe it has something to do with that.
