I have a book on spiritual warfare prayer, it has a list of angels and there roles in the kingdom.
Mighty Angels-These are heaven's warriors-God's fighters (see Ex 33:2 & Rev 10:1)
Guardian Angels-New converts(guide them)

Elect Angels-Ministers to the need of the church(see Acts 12:11)

Archangels-To remind us of the coming of the Lord
end time prophecy
that our time is short (see Zech 1:13)

This is a really good book, its not about angels, iits about expanding our prayer time. The author is Judy Doughty. She is a very good teacher, she was guest speaker at my church a few years ago for our ladies retreat.
