I believe there is more than one god.

I believe that there are people who believe in multiple G-ds, and I don't think those people are wrong per se, but I don't believe in them. Personally I think the way most people believe in G-d or G-ds is a little silly. The idea of an invisible magic man who can read your mind, knows all and can help you with magic beans always seemed goofy since I was a kid.

Well, the idea is much more viable with the pretence that the "magic man" created this whole shebang, including you yourself.

I think that everyone worships something(s) and that all of these collective prayers ultimately reach the same destination of God.

And no, God can't see inside your head (according to my beliefs).

Can you imagine for a moment what the universe would be like if there were more than ONE God. Imagine the committee meetings; God1, "i get even eons in odd numbered galaxies." God2, "no i get even eons in odd numbered galaxies." Who is right and which God is more powerful than the other?
What if two ganged up on one? That is just too complacated an idea to me at least. IF there is a god there is only one god, any more than that would make the universe even crazier than it seems.

Is God like a swear word now or something?

Of course there is but your creater wants you to only acknowlage him down here.....(wants total credit) understandable

It really does depend on the day, whether I think of my faith as poly/pantheistic, or whether I think if it as abstract concepts.

the Bible mentions many "gods"
they are called demons today
but many still worship them as gods

Actually, that isn't true. The only G-ds mentioned in "the bible" (which I presume refers to the old and new testaments, usually the king james or a modern retranslation of it) beyond He-Shem if by which you mean the old and new testaments, are the references to the statues of the polytheists in Genesis who could not take action, and were thus destroyed.

There is theoretical reference to "the adversary" in one or two texts (depending partially on your context) which commony adopted apocrypha seems to believe refers to Lucifer the light bringer. Though this isn't agreed upon in all Christian sects. The only reference to such a position in the "old testament" is in Job. Rabbis and scholars discuss who the adversary might be and exactly what their impetus is.

Modern Judiasm doesn't believe in the existence of demons. I find the idea of any imaginary beings who use magic jujyfruits to alter reality based on a whim to be an absurd escapist fantasy.

All hail to Dogar and Kazon!
