If the Hubble telesope can look back about 13 billion years and takes pictures of 100's of galaxy's all clumped together, is it possible for the Hubble to look in another direction and take photos of the same galaxy's it took the first time?

Only if the universe is smaller than the observable universe:

If the universe is finite but unbounded, it is also possible that the universe is smaller than the observable universe. In this case, what we take to be very distant galaxies may actually be duplicate images of nearby galaxies, formed by light that has circumnavigated the universe. It is difficult to test this hypothesis experimentally because different images of a galaxy would show different eras in its history, and consequently might appear quite different.

These were open questions decades ago, as the possibility remained that the Universe were finite and small enough. Presently it's considered probably flat and definitely bigger than our horizon.

 

One suggestion: have more recent books, this saves time. You don't have to learn and de-learn abandoned theories.
