Fallen angels and demons are evil entities. They have the ability to deceive people. Both these entities are usually considered the same but there is a difference between the two.
To begin with, fallen angels are more powerful than demons. Basically, they are the sons of God, or you can say the angels who rebelled against God and as a result, they were banished from Heaven. Demons, on the other hand, are disembodied spirits.
Fallen angels have their own celestial bodies. Hence, unlike demons, they need not possess other bodies. Demons, on the other hand, are wicked and unclean spirits and seek the possession of a human or animal body.
In addition, fallen angels, also known as Satan’s ministers, can transform themselves and pose as ministers of righteousness. Moreover, they can travel out of this world and manifest themselves physically in front of people.
Demons, however, though unusually powerful in physical strength, have limited physical movement. Unlike fallen angels who can fly, demons can only walk. Demons are believed to be the disembodied spirits of the Nephilim who are the offspring of fallen angels and humans.
Plus, it is to be noted that one can rebuke a demon to drive him away but, this cannot be done in case of a fallen angel. So, when dealing with a fallen angel, one needs to drive the evil entity away by asking God to rebuke it rather than doing it personally. The archangel Michael had done the same.
“But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not himself dare to condemn him for slander but said, “The Lord rebuke you!”
~ Jude 1:9
In case you are wondering about the difference between fallen angels and holy angels, suffice it to know that the fallen angels do not obey God and give glory to themselves whereas the latter are obedient to God and encourage us to do the same.
Thus, Satan and his angels give us instructions that are contrary to the Bible. Angels, on the other hand, glorify God and instruct us correctly in order to help us love God more deeply.
Furthermore, holy angels do not long for acknowledgement for their works; rather their actions are solely motivated by their love for God. Fallen angels, however, try to oppose the believers.
