God's Word/the Bible says many things about Angels, about one third of God's Word has/is about Angels. Angels shouted for joy at the creation of the heavens and the earth, Job 38. Cherub Angels guarded the way to the Tree of Life in Genesis 2 after the sin and fall of humans. Angels intermediated the Law being given to Moses in Exodus 20, Galatians . Angels announced the birth of Christ Jesus, Prophesying it before it happened. Angels were at the empty tomb, announcing Jesus' resurrection. Angels are involved in many things in the Book of Apocalypse/Revelation. They are very much involved in life.
Psalm 91 says that God commands His Angels concerning those who Believe Him/in Covenant with Him and Trust in His Name. Many times in the Old Testament/Covenant God sent His Angels to Prosper, Protect, Guide, etc. His people. In Acts 12 Peter was Miraculously freed form prison by an Angel and when he showed up to the house that was Praying for his arrival, they were so stunned that they thought it couldn't be him but must be his Angel. Jesus said "See that you do not despise one of these little ones. For I tell that you in Heaven their Angels always see the face of my Father who is in Heaven," Matthew 18. So, we See that yes, Angels are sent to Guard little children, and people in Covenant/now through Jesus with God, and that they affect the events of humans as ones on the side of God and His Army, opposing the devil and his army.
To Interact with Angels is found many times in God's Word. This however must therefore be in Right Order, so that we do not worship Angels (Colossians 2), or get deceived and/or oppressed by demons disguising themselves as angels of light (2Corinthians 4, 11), etc. So, first and foremost in this Order is being in Covenant with God the Father through God the Son Jesus, because this transfers us from the side/army of the devil and his demons to God's side/Army and His Angels, and Forgives and Purifies us of our sin (lying, stealing, bitterness, envy, etc.) which is a main open door/way that demons oppress humans. Also through walking with God by His Holy Spirit then we can have Sound Discernment to Know what is of God and what is not, or what is an Angel and what is a demon, and so on. From there we must make God and our Relationship with Him, Worshiping Him, etc. our first and foremost thing that we do and are Centered on, then out of that can Flow the Rest of Life, including God's servants that are Angels/Spirit Beings He Created. This can happen through multiple means, such as Prophetic Dreams from God, Seeing in the Spirit Realm by Holy Spirit, using our Spiritual Senses and/or coupled with our physical senses, in times of Prayer when Heaven moves in response to our Prayers to God, and more, all found in God's Word. I have Sense and Experienced both Angels and demons many times, sometimes even with my physical eyes I have seen them wrestling and fighting over me, or Angels Protecting and Serving me for God. Thus Confirming God's Word by Experience. Grace and Peace to all in all these things to have your full Destiny and Inheritance, in the Name of Jesus Christ, Amen.
@Lord Enki I See that you have a lot Passion, and I Honor that. However, you seem very sure and cut and dry with your answer, like this is the only way it is, but Life is very multifaceted. And, the Greek word is not "Anglos" but "Aneglous" from "Angelos" that can mean "Messenger as an Angel/Spirit Being, or human, depending on Context." The Hebrew
