How do you file criminal charges and get 2 people arrested?
You don’t. In the u.s. there is no private criminal prosecution. If you have knowledge of a crime, you can notify the police who will conduct the investigation. The police will then send a report to the DA and the DA will decide whether to use taxpayer money to seek a criminal conviction. Some of the things you describe are federal matters, if interest to federal authorities, and some are state crimes. Slander is not a crime at all. Neither is harrassment.
