Yes, there is water on one, and volcanoes active on another.
no
Europa has frozen oceans.
Yes. If it were life like we know it here on earth, it would have to be located deep in Europa's ocean near thermal (heat) vents in the ocean's floor.
Venus has no moons.
yes europa has an icy surface but underneath theres underwater volcanoes that warms the ocean. plus theres some oxigen which now scientist belive that there is aquatic life there.

At the moment, none. In the future, when we some some evidence, I'm sure this answer will be updated. 2nd Answer: Although we do not know if there is life on the moon Europa, most scientists agree that life could arise and exist deep in Europa's ocean near thermal (heat) vents in the ocean's floor.
we could have a very long nights with two moons together appearing in the sky.and also the scientists would have to go to 2 moons
Not yet, but, as we have discovered water on various planets and moon, the possibility of life - as we know it - does exist.
Water
Europa is 1 of Jupiter's 63 moons, one of the four Galilean moons, and it is important because it could posssibly hold life.
We have no way of predicting accurately where intelligent life can exist, we can only predict where human or earth-based life can exist. Life is a self-repeating chemical system, and it can potentially exist in any solar system, even on frozen moons that still have warm cores. Life that would be truly "alien" to us might even exist in the cold, seemingly dead space between stars, we can't know.
