We can't really know what angels are like. They do not
have Human bodies like us. They are spiritual creatures
with spiritual bodies. They could appear in human
other forms.

Angels are generally shown as ethereal human like
beings. We really have no alternative. There is no way
to adequately describe an angel.

Angels do not have a gender. They are often shown as
females. Probably because the female figure is
universaly consideded beautiful.

Angels do not necessarily have wings. I guess in the
time period of Greco Roman divinities, wings were
associated with the ability to fly.

In most cases they do not have halos, which are
symbolic of divinity. A god like quality.

I take angels to be perfect humans if we were perfect.

Since they are imortial, health and old age would not
be an issue.

They have no sexual desires, since it is not necessary
for reproduction. Sexual desires cause humans a host of
problems.

Since they are perfectly happy all the time, there is
no need for alcohol or drugs.
