Why is this not recommended for acrylic aquariums?

My guess is bc acrylic scratches a lot easier.

If i wanted to cut this in half, how would i go about safely doing it? it was bigger than i thought

The rock is hollow inside. If you cut it in half there will be a big hole in the middle. It is resin material, you can easily reshape it with a hand saw. Just make sure to avoid cutting the magnets.

Could it work just a a rock to hold frags on the sand bed or would it float?

It’s heavy enough it should not float

Are the magnets on the other end waterproof?

Yes, wet side and dry side magnets are all waterproof sealed. From Reefing Art Team
