The dance where he drags one wing & walks sideways is a hay look at me dance. He wants the hen to stop so he can do his thing. When he climbs on top & grabs the back of there head he is doing his thing. For the kids chasing I would have to say that is a bad thing. He may start fighting back. Most of the time unless they have some game in them they don't fight people if treated right. He must never get one up on you though. If he starts pecking you then pull a feather from the back of his head or hold him to the ground & pull his head back. Mimic what he is doing to the hens & make sure it is in front of the other birds. If you embarous him that will go much farther then fighting him.
