In the Holy Church’s traditional calendar, this week on September 29 we celebrate the Feast of St Michael the Archangel.

In the newer calendar, all three archangels, Michael, Gabriel and Raphael, are celebrated on that same day. On October 2 we revel in the feast of our Holy Guardian Angels.

Speaking of archangels, the aforementioned are the only three angels whose names we have from Holy Writ. In 1982 the Holy See’s Congregation for the Doctrine of the Faith told us not to invoke by name angels other than those three. It’s probably OK if you want to nickname your own guardian angel. Just don’t get into invoking unknown angels by names that we cannot verify from divine revelation.
