Lets see what a quick search gave me from some well known hindu sages:

Angel is a divine messenger, or son of God. He corresponds to the
Deva of the Hindus.

According to the Puranas, the isolated sparks are the divine radiance of what we call the
gods or angels of heaven and the higher realms of being. The Aitareya Upanishad makes a pertinent point when it says that these
angels cried aloud, being cast in the ocean of hunger and thirst and wanted food for themselves, which they craved from the Creator…

Krishnananda writes:
All the energies and all the senses (Prāṇa), everything that we call mentation, understanding, or intellection; all these worlds (Loka), the various realms of being; all the celestials (
Deva), the
angels in paradise; all the planes of existence, everything created, whatever is called a created being (Bhūtani); – all these are emanations from the Absolute Self. That appears as all this multiplicity.

The performance of worship, in religious parlance, to
gods, deities, angels, or whatever we call them, implies an inward attunement of ourselves with a transcendent principle which lies between the subject and the object, ourselves and the end which we are aiming at.

An indication of these experiences is given to us in the Taittiriya Upanishad, for instance, where we are told that above men are the Pitris, above the Pitris are the Gandharvas. Then we have the
Devas, or the gods, or the angels, then the ruler of the angels called Indra, then the Guru or the preceptor of the gods, called Brihaspati, the great repository of wisdom. Beyond that stage is the Creator. Such details of the existence of higher realms of experience are available in scriptures of this kind not only in India, but also in other countries.

Ramana Maharshi says:
D.: Why then did the bathing
angels don clothes when he appeared before them, but not when Suka passed?
M.: That same Vyasa sent Suka to Janaka for instruction; Suka was tested by Janaka and finally he returned convinced of Vyasa’s greatness.
D.: Is there any way of sensing super-physical phenomena, e.g., guardian
angels?
M.: The state of the object is according to the state of the seer.
“Talks with Sri Ramana Maharshi”
Vivekananda writes/talks:
Even forgiveness, if weak and passive, is not true: fight is better. Forgive when you could bring legions of
angels to the victory.

The fountain of all knowledge is in every one of us, in the ant as in the highest
angel.

Aurobino writes:
…in the present and in his attainment a little lower than the
angels, yet in the eventuality and in his culmination considerably higher than the
gods.
