A god for every day of the week.
As to modern times - depends what religion. The is only one Christian God, but there are many types of Christians. That is a question of doctrinal differences. They all essentially believe in the same thing, they just all believe in approaching it differently and thus it seems like there are many Gods.
Same with Islam, and to a lesser extent Judaism.
Buddhism is a different kind of belief when it comes to God/gods.
Hinduism has a huge pantheon, and they are mostly representational gods representing aspects of the natural world and/or human concepts (similar to many ancient religions)
Neo-pagan has a tendency to come up as a re imagining of traditional pagan religions of old, while mysticism, crystal worship and so on differ again.
