How do astronomers observing distant galaxies talk about looking backward in time?
The speed of light is not infinite. Light takes time to travel from distant galaxies to our eyes here on Earth. If a galaxy is 1 billion light years away, it has taken 1 billion years for the light emitted by said galaxy to reach us here, so (obviously) we are seeing the light emitted 1 billion years ago. In a sense, we are seeing 1 billion years into the past at the light emitted by that galaxy.

The number of stars in a galaxy depends on its size.
The Milky Way Galaxy has between 200 and 400 billion stars. Dwarf galaxies may contain as few as 10 million stars, while the largest galaxies consist of more than a trillion. This is usually due to the merging of smaller galaxies into one big galaxy.
There are an estimated 100-300 billion galaxies in the observable universe.
