The Buddha uses 'deva' (male) and 'devi' (female) to describe virtuous people in AN 4.53
"Householders, there are these four ways of living together. What four? A wretch lives
together with a wretch; a wretch lives together with a female deva; a deva lives
together with a wretch; a deva lives together with a female deva.
And how does a wretch live together with a female deva? Here, the husband is one who
destroys life, takes what is not given, engages in sexual misconduct, speaks falsely,
and indulges in liquor, wine, and intoxicants; he is immoral, of bad character, ....
he insults and reviles ascetics and brahmins.
But his wife is one who abstains from the destruction of life, from taking what is not
given, from sexual misconduct, from false speech, and from liquor, wine and intoxicants,
she is virtuous, of good character, .... she does not insult or revile ascetics and
brahmins. It is in such a way that a wretch lives together with a female deva."
[BB, TNDB, page 443, part of AN 4.53]
This is similar to the way that a virtuous woman might be called 'an angel' in English.
Do devas exist? Yes, of course they do!
