I can't speak for all of the 30,000 + denominations of Christianity, nor the multiple versions of Islam and Judaism, but I'll try to briefly summarize the Abrahamic perspective.
There is only one God. Not one God bigger or better than the others, but only one. All the rest, including all the millions of different versions of Jehovah, are fiction. Not real. Nonexistent. Symptoms of human consciousness.
It is tempting to think of those things as real beings with real power, who respond and interact in a godlike manner. It is tempting, but it's wrong. When we choose to follow wrong things under false assumptions, we end up in bad situations. If we think God loves killing people, we end up killing people. If we think God likes strippers, we get a religion of strippers like they had in Babylon. If we think God is about being the biggest best and baddest, we get patriarchal cults with infant sacrifice and slave labor. Every time we try to pin down God to a set of human-like identities, the culture founded on those beliefs becomes an evil monster that sometimes doesn't go away until natural disaster wipes it out. Whenever you find people engaged in mass atrocity, you can be sure it is rooted in their beliefs about how the universe is governed.
You can believe in any deity you want, and you will find a mountain of reasons to think that it's real. The real God is always going to be a step beyond comprehension, hence the term "ineffable" applied to it in the lore of magic. Something so grand has no problem relating to you as a father, as a brother, as a friend, or as some squid monster or period-costume character if that's how you approach it.
