  What are the distances between the galaxies? One could be in fact trillions of light years away from the other.

  Oooops, not trillions of light-years. The Universe isn't that big. see this link

  Usually tens of millions or hundreds of millions.

  You can guess distance by the colour. of the galaxy. You can also click on Photoz, which is a computer's estimate of distance based on colour. Sometimes that is guess is better than a humans, sometimes it is way off, but it always has big error margins.
