You put 10 questions into one. You cannot do that. I have chosen the first 1-part question on your list to answer. If you want the rest answered, you can submit them one at a time.
Mr. Hale is a preacher from Beverly, a neighboring town. John Hale had an experience recently which made him think that the had exorcized an evil spirit from a woman. However, this is not the case. If he himself took a broad look at the situation, he would see that all he did was take the woman's victim, give the victim some food and tender loving care and then the victim was okay.
Thus, he thinks he is qualified and he has self-educated, but he is not qualified.
He has no experience with the Devil, the occult, or getting witchcraft out of people, or even discerning witchcraft. But he has certainly read much about it. He thinks because he is so well-read, he knows what to do. In fact, the audience recognizes how heavy his books are and a play on words is made as he enters that they are "weighted with authority" meaning that God inspired them.
As editors, we are allowed to answer only one question at a time. I would suggest that you reread the play and then go to the link below to get help with your study guide. Getting together with a classmate to discuss the questions would also be a good option. If you have a particular question you still have problems with, please don't hesitate to ask us for help.
