I'm currently away from my copy of Max but if I remember correctly you can un-child something by going to schematic view. It's the button towards the right end of the tool ribbon, has two rectangles with a downwards arrow on it. That should open a new window where you can choose the bone you want to move. Once it's in position to child it again.
To un-child and reconnect, I think there are two buttons in the top left of the schematic view that look like a broken chain and a solid chain.

With the default Bones system, you can use Bone Tools.
