Angels are winged creatures mentioned or witnessed throughout the Warcraft universe. They are rarely referred to specifically as "angels". It may be possible that Angels later in the game universe are a different species not really the same Angels that appear in the early Warcraft Universe, but instead appear to be Angels as a practical conception by their appearance thus called Angels. In the early games, Angels appear to be armored beings as opposed to spirit healers who lack armor. Tyrael resembles an armored old angel and not a spirit healer.

The first reference to angels exists in Warcraft I manual:
As the archangels took up swords of light to defend the heavens, so must we take up holy arms to defend our lands.
Warcraft IIThis section concerns content exclusive to Warcraft II.
The second reference to angels is seen in Warcraft II manual:
As the guardians took up swords of light to defend the heavens, so must the holy men of earth be prepared to combat the dark tide that was quickly approaching from the south.
This example is probably referring to guardian angels, the archangels from WC1, rather than the Guardians of Tirisfal who have never been to the "heavens".

It is said that when the divine spell, Mass Revival, is cast, it summons an angelic form to appear as the caster's fallen allies rise again.
When the spell Divine Ascension is cast, the caster transforms into a "beautiful", angelic version of themselves. Their skin, hair, and nails change into metal — silver, bronze, or gold, and they gain the ability to cast healing faster. The spell sounds similar to the Spirit of Redemption, which also causes the priest to transform into an angelic being.
