Space or Ether are other names used for the 5th element which can be similar to Void. It's kinda like a base and bridge for the Space-Time link. Time is kinda tricky though since it technically is non-existent (kinda like void). So therefore I think it would fall under the category of "5th element abilities" although it is not really definitive of void, space, or Ether but more of a result of them.
When you say he's the only male does that mean there are others who are all females? I picture some power dealing with either attraction/seduction, solar, or some sort of universal magnetism (or all). But I see this dude being a magnet to the female heroes (and villains) whether he wants to be or not and getting himself into all kinds of crazy situations with it ? but learning to harness his powers through these experiences.
So hallows would definitely be a sub category of spirits
I think spirits can be a part of undead in the case of reincarnated souls into "dead" physical bodies but not sure that a hallow is undead since it's body is technically made of signature of spiritual pressure.
Hmm not sure if it would be a whole new power category, but if it were perhaps "spirit monster/beast" would be an appropriate name if that isn't already one.
This is a good question...since it is an ascendant type beast but i think hallows would fall under a category that is not quite divine. I feel as though it would be an opposite to divine beast in a sense but not necessarily demonic either

All of the above, but if you're talking which ones are most alike/related: lightning/super speed and invulnerability/water
