Some angels, usually higher ranking, have been depicted with multiple sets of wings. Metal shards that spark and thunder could be some sort of draconic or a thunder bird. Try to meditate on each pair and just record any images or sensations you get. If you’re more then 2-3 things, that could be causing a lot of the confusion. Blending of so many energies can be difficult for human bodies and minds to comprehend. So just try to isolate your feelings and feel every aspect of yourself 1 at a time.
