Can a family member who is a minor be a witness in a physical dispute and testify in court against one of the party''s?

There are no Arizona laws that prohibit minors from testifying in court about what they have witnessed.  The witnesses credibility (their truthfulness) will be judged by the finder of fact (either the judge hearing the case or a jury).  *The answers are for informational purposes only and do not create an attorney-client relationship between the question presenter and Laura B.
