No, my friend. There is only one God. One. Other gods are false gods, which is why we are not to worship them.
Isaiah 45:5
I am the LORD, and there is none else, beside Me there is no God
Remember the showdown between Elijah and the priests of Baal? How the priests of Baal couldn't get their god to respond (because he doesn't exist) and even though Elijah drenched the altar with water, God sent down fire to consume the offering.
The "dragon" and his "beast" (Revelation 13) (Daniel 7:24-25) was to deceive "those who dwell on the earth". The dominion of the beast still reigns (Daniel 7:26). The god of the beast/beasts, were the pagan gods, and the god of the beast with two horns like a lamb, Constantine, was Sol Invictus, the sun god, who provided his authority to the beast of (Revelation 13:4), Caesar, who was the source of Constantine's authority. The men of renown, the descendants of the heavenly watchers, the "sons of God" (Genesis 6:4), and their fathers are those who hold the position of gods. The beast/kings, apparently have authority as they will rule the world until Daniel 2:44-45, when they will be crushed, and that would included the kingdom of Cyrus, the breast of silver (Daniel 2) who is the subject of your Isaiah 45. The prince of the kingdom of Persia was withstanding Michael, the chief prince.(Daniel 10:13), and this was a heavenly/spiritual battle fought because of Daniel's prayers and fasting. (Daniel 10:3).
As for Baal/Bel, his priest seemed to have had terminal day, but in the case of the priest of Egypt, they could also turn a staff into a snake. The problem being that Moses snake ate the snake of the Egyptian priest. Apparently the God of Moses had greater authority than the gods of Egypt. The gods, such as the sons of God, including "Satan" had their place, as Job was to find out. (Job 1:6) Just because their power is inferior to that of God, does not mean that they do not exist. As Isaiah 45 pointed out, there is one God, who is the creator, and apparently as creator of heaven, he created sons of God (Job 1:6), who actually exist, and are worshipped by the sons of men, as gods. Do the sons of God, such as Satan have power and exist? Ask Job what he thinks.
