Could the moons of a Gas Giant all be habitable if that planet was in the habitable zone?

I ask this as a basis for a World (in this case Moons) Building I'm doing. I came up with a couple of different problems and some possible solutions to those problems:

• All of these questions presume the moons are artificially created or modified by a far superior race and placed into orbit artificially. That being said, they can bend physics, not break it. So I'm asking these questions based on that idea.

• If the moons orbited on the ecliptic, there would be protracted periods where the moons would be eclipsed from the primary. Unless... they orbited in a circumpolar fashion. Would there be any problems with this? If circumpolar was too far fetched or had hidden physics problems, could the axis of rotation of the jupiter style planet itself be close to that of the ecliptic so its moons would orbit in a manner similar to circumpolar?

• Could multiple Earthish-sized moons with an Earth-like atmosphere exist in orbit around a Jupiter-sized Gas Giant? Or would the tidal pull strip the atmospheres?

• Assuming the moons had active tectonics like Earth, would the magnetosphere of these moons be strong enough to protect those living upon it?

• Can you identify any other problems livable moons circling around a gas giant would have?

TIA.
