Yes they can. Devas help the good and the other "demigod-like" beings (like asuras and even ghosts) as well based on one's karma. If one does good, they can help that being (they are attracted to the good karma). If one does evil, asuras can haunt that being (they are attracted to the evil karma).

Yes they can. If one does good, particular "higher" beings (including Buddhas) can more easily help that being (they are attracted to the good karma). If one does evil, asuras can more easily haunt that being (they are attracted to the evil karma).

Let's keep it short... Above all, remember that there are many other properties to them that are completely irrelevant to your Buddhist tragedy (1st Noble Truth) and the importance of meditation and Enlightenment with your precious life-time. Thus to answer your last question... yes it is compatible but also remember that Hindus also believe in this stuff. The difference with Buddhism from all (inferior) traditions is there exists Buddhahood for the sake of all beings and the Three Trainings and this has little to do with over-concern for worldly matters (e.g. Mythbusters and other obsessions with paranormal phenomena). The Buddha himself said this and so did Confucius (who had Enlightenment).
