The
malak Yhwh (‘Messenger/Angel of Yhwh’) or the malak Elohim was apparently thought to have a human form. In fact, a good deal of the angels that appear in the Bible really seem to appear as humans (in Tobit, in fact, the angel Raphael disguises himself as a man); the only thing that marks these messengers as not being regular humans in some instances are their white clothing. (For example, the men in linen of Ezekiel or Daniel or the angels who appear in Jesus’ tomb in the gospels.)
Only the cherubim and the wheels in Ezekiel, the seraphim in Isaiah, and the living creatures in Revelation are really described as being non-humanoid, even sort of eldritch abomination-y, in form. (I’m not counting Abaddon/Apollyon or that “mighty angel” that has John eat the open scroll.) And yes, these are the only ones that are expressly said to have wings.
Ezekiel’s four cherubim each have four faces (a human, an eagle, an ox and a lion) and four wings with eyes, human hands, the feet of a calf. They are accompanied by wheels-within-wheels (
ophanim) covered with eyes. Isaiah’s seraphim has six wings: “with two he covered his face, and with two he covered his feet, and with two he flew.” (They apparently have hands as well, since one of them touches Isaiah’s lips with a burning coal it held in its hand.) The four living creatures of Revelation are like a combination of Isaiah and Ezekiel: a lion, a calf, one that “had a face like that of a man,” and an eagle that each has six wings and are covered with eyes.
