Wow. That's a tall order with all those entities. Perhaps it's easier to reach the angels of the entities at that site (or perhaps just the one who's reached out to you?). Maybe you can ask the angels what's going on and if you can help.
What you're describing is amazing that someone's reached you (the group is probably ready to be helped after all this time), but it also sounds a bit overwhelming if you've never done something like this before. And if you can find someone else here on the forum to help you, or at least to explain what's happening, it'll be easier all around.
You could also ask for the light to go to all of them, and explain that you don't know how to help them, and ask them to find someone else in the light to help them.
Another option is to go to Archangel Michael and ask if there's something you can do for them and/or ask him to assist all the entities into the light.
Just a few suggestions, if any of these sound like something you might like to do. It's also amazing that you're receptive enough to notice this contact going on in the first place. That's definitely something not everyone can do (at this time).
