How do angels help humans?

The angels help us in many ways, such as often protecting us from physical danger. More importantly, however, angels can help us in regard to sin. St. John Bosco said, “When tempted, invoke your angel. He is more eager to help you than you are to be helped! Ignore the devil and do not be afraid of him: he trembles and flees at the sight of your guardian angel.”

Also, angels help us at the end of our lives. St. Alphonsus Liguori said, “The powers of hell will assail the dying Christian; but his angel guardian will come to console him. His patrons, and St. Michael, who has been appointed by God to defend his faithful servants in their last combat with the devils, will come to his aid.”
