Islam acknowledges the existence of angels.
Angels are a non-rational matter, but their existence can be shown to be reasonable, i.e. coherent within its own frames of reference. They are not rationally demonstrable in the sense of being captured in a test-tube or in a Petri dish.
Angels are second only to Allah as a principle of belief, and without them, it is not possible for God to be known. They are, in a sense, integral to divine unity: without angels, God's names and attributes cannot be perceived or fathomed. So they're important conceptually and they're an important conceptual bulwark against the secularism of faith that is such a problem these days.
Several are mentioned in the Qur'an and others in the hadith literature.
Angels are not equal in status, delegated different tasks to perform.
The angel of revelation who was responsible for revealing the Qur'an to Muhammad (saw). He communicated with all of the earlier prophets and messengers, also descending with Allah's blessings on the night of Laylat al-Qadr (the night of Destiny).
