Alrighty! Sounds awesome!
Here a couple of names I could think of based of those descriptions:
1st Band: The Good Luck band, Band of Good Fortune, the Karma Binta, Reflector *or Giver* of Good Will.
2nd Band: The Band of the Holy Aura, Divine Aura Band, The Protection of the Good, Band of Holiness.
3rd Band: Hmm...this one is a bit tricky because of the description. You probably want it to be something meaningful, so I would recommend seeing what kind of relationship Yana had with her Grandmother and the reason why it was passed down and what would be the purpose of it.
These are just a couple of brainstormed names that came to mind; sorry if it's not what you are looking for. I'll keep looking for more for your assistance.>.>
