Who are the Guardian Angels?

They are our great allies, we owe them a lot and it is a mistake that we talk so little about it.
Each of us has his own guardian angel, a faithful friend 24 hours a day, from conception to death. It unceasingly protects us in soul and body; and we mostly don't even think about it.
We know that nations also have their own particular angel and this probably also happens for each community, perhaps for the same family, even if we are not sure of this.
However, we know that angels are very numerous and eager to do us a lot more good than demons try to ruin us. Scripture often speaks to us about angels for the various missions that the Lord entrusts to them.
We know the prince of angels, St. Michael: even among the angels there is a hierarchy based on love and governed by that divine influence "in whose voluntate is our peace", as Dante would say.

We also know the names of two other archangels: Gabriele and Raffaele. An apocryphal adds a fourth name: Uriel.
Also from Scripture we derive the subdivision of the angels into nine choirs: Dominations, Powers, Thrones, Principalities, Virtues, Angels, Archangels, Cherubim, Seraphim.
The believer who knows that he lives in the presence of the Holy Trinity, or rather, has it inside him; he knows that he is continually assisted by a Mother who is the same Mother of God; he knows he can count on the help of angels and saints; how can he feel alone, or abandoned, or oppressed by evil?
