High Elves and the Balrogs

[Boromir88]

Raynor, with regards to protecting Lothlorien I would say she had the aid of Nenya. As that was the purpose of the Elven Rings. However, the Elven Rings were not made to enhance it's bearers power, so any display of power 'or magic' of Galadriel I would say was all her own ability. As the Elven Rings did not lend out power boosts in the way the One Ring was made to do.

Just as I would argue the benefit of Gandalf bearing Narya was not in giving him extra power to fight the Balrog, but assisting him in his 'weariness,' exactly as Cirdan said the Ring was for:

'Take this ring, Master,' he said, 'for your labours will be heavy; but it will support you in the weariness that you have taken upon yourself. For this is the Ring of Fire, and with it you may rekindle hearts in a world that grows chill.'~Appendix B: Tale of Years; The Third Age
