would they all be the same age or would some be older than others? Do we really even know?

There are Old Galaxies In The Young Universe
Current theories of the formation of galaxies are based on the hierarchical merging of smaller entities into larger and larger structures, starting from about the size of a stellar globular cluster and ending with clusters of galaxies.
According to this scenario, it is assumed that no massive galaxies existed in the young universe.
However, this view may now have to be revised. Using the multi-mode FORS2 instrument on the Very Large Telescope at Paranal, a team of Italian astronomers have identified four remote galaxies, several times more massive than the Milky Way galaxy, or as massive as the heaviest galaxies in the present-day universe.
Those galaxies must have formed when the Universe was only about 2,000 million years old, that is some 12,000 million years ago. The newly discovered objects may be members of a population of old massive galaxies undetected until now.
The existence of such systems shows that the build-up of massive elliptical galaxies was much faster in the early Universe than expected from current theory.

When did the first stars and galaxies form after the Big Bang occurred? The answer---very quickly! Scientists have found the first direct evidence that galaxies as large as the Milky Way already had formed when the Universe was less than a billion years old.
They have actually have viewed these very first galaxies at the edge of the observable universe.

I don't know how old all of the galaxies are, but the oldest galaxy is 13.2 billion years old with a redshift of 10.3. The name of the galaxy is UDFj-39546284 .

The same age i hope

nobody knows and the big bang theory is fake

dude ! Nasa don't know , how we should know ? lol
