My own child is 6 years old and he does not do any of those things. That is not normal behaviour, any of it. If it was me, I would be having a long talk with his parents and finding out what they are doing to change this behaviour in him--and if they are not putting in the effort to help him, I would terminate. If a child isn't being taught how to behave at home nor being appropriately disciplined, you aren't going to be able to help him all on your own--you need the parents on board.
