As already mentioned, there is a distinct lack of a developed demonology in the tradition, and therefore in the Church.
However, I can see such things as being semi-logical
speculative developments. I have heard it said (though I cannot as yet determine the “validity” of such a teaching within the Church itself) that the demons/fallen angels try to imitate (for reason of perversion) the Orders instituted within the Celestial Heirarchy, and being “angels” themselves, it is not unreasonable to suggest that there are particular demons who “specialize” in particular sins, in the case of the Succubi/Incubi, Lust.
However, as these beings lack the physical faculties necessary, as the MM actually got right, the creation of Cambions is not really possible. I suppose the
closest one could get would be in the intercourse with a possessed individual; otherwise it is pure occultic superstition, the resulting “fruit” of cambions being anything but
physical humanoids.
Additionally, as angels (and therefore demons) lack a sexual basis, it would be inconsistent to divide the Succubus and the incubus into two
distinct classes of demons, a single demon would itself be both, with the Succ-/Inc- prefix being malleable “descriptor” to fit the specific instance in relation to its victim.
The issue of the nephilim is a little complex from the Church’s perspective, as it denies that they were 1/2 breeds as commonly understood (well, “commonly” within that small group of people who know anything about them

)
But, as a reminder; outside of the “fact” of their existence, everything else is essentially “Speculative” theory with regards to demonology. Even the Church’s angelology, far more developed and bound by Tradition, has many speculative components.
The Opus Angelorum has some good references for what the Church teaches definitively regarding Angelology and Demonology. My personal favorite is “Deliver Us from Evil” by Fr. Basil Nortz, ORC as it contains recent teachings (from JP II), the Catechism exerpts, Cannon Law exerpts, ect, as well as a variety of prayers for both honoring the angels, and appropriate ones against demons. Another good, if small, book is their “Little Catechism on the Angels” which provides the relevant De Fide positions regarding the subject, in addition to the catechism and other resources.
