Note that for simplicity's sake, Lucifer has been classified as a devil. But like many of his ilk, he is also a "fallen angel." As such, Lucifer could certainly be grouped with angels as well. This is a particularly important part of Lucifer's character, more so than with many fallen angels who are now devils.
