Note 3 at Ac 21:31: These were not the believing Jews, whom Paul and the elders sought to appease, who were trying to kill Paul. These were the Jews who had rejected Jesus as Messiah. Paul's defense in Ac 22 was of the Christian faith as a whole, not just a defense of grace versus Law for salvation.

Note 4 at Ac 21:31: As explained in note 3 at Joh 18:3, a band of soldiers was 600 men. A captain or centurion (see note 1 at Mt 8:8) ruled over each 100 men; therefore, this band had six captains. This man, named Claudius Lysias (Ac 23:26), was the highest-ranking captain of the six.
