Scott,
Demons:
"In Scripture and in Catholic theology this word has come to mean much the same as devil and denotes one of the evil spirits or fallen angels. And in fact in some places in the New Testament where the Vulgate, in agreement with the Greek, has daemonium, our vernacular versions read devil. The precise distinction between the two terms in ecclesiastical usage may be seen in the phrase used in the decree of the Fourth Lateran Council: "Diabolus enim et alii daemones" (The devil and the other demons), i.e. all are demons, and the chief of the demons is called the devil. This distinction is observed in the Vulgate New Testament, where diabolus represents the Greek diabolos and in almost every instance refers to Satan himself, while his subordinate angels are described,. . ."

Most religions have similar teachings. It is not ambiguous at all.
