When Matthew was written, during the eighties of the first century, and even later when Luke was written, it was no longer a problem for Jesus to be referred to openly as the Son of God. Christianity and Judaism were parting company and the gospels no longer needed to consider Jewish sensitivities. Luke 4:34 was copied more or less verbatim from Mark 1:23, so keeps the reference to the unclean spirit calling Jesus "the holy one of God."
Unclean spirits were demons or devils that entered into a person and controlled his actions and thoughts. This may or may not have had physical manifestations.
From the power of God.
They were the lepers.
Read the related answers on this topic. But Jesus said that spirits do not have flesh and bones, (Luke 24.39), though they may take on any form or smell as the unclean spirits in Revelation 16.13

Peter
The purpose of Jesus' miracles was to show He was God in the flesh. Through the miracles He showed He has power over sickness, disease, the natural realm and in Luke 4:31-37 Jesus showed He has power over the spiritual realm. The people present could see He has authority and power over spirits: Luke 4:36 Then they were all amazed and spoke among themselves, saying, "What a word this is! For with authority and power He commands the unclean spirits, and they come out."
The bible tells us the Jesus created everything. Human spirits originated from God (Jesus) and they return to God on the death of the physical body.
Ghosts, or the undead.
have faith in god and always utter the word jesus christ to ward of bad spirits!!
No, He cast out evil spirits. That is very different from having long conversations with spirits about people's lives.
