It means there are two H2O molecules

Di=2
Aqua=H2O

So, Diaqua would be (H2O)2

you would use aqua when the water molecule is acting as a ligand bound to the central metal atom, in which case the H2O would be found within the brackets in the chemical formula. Hydrate is used when the water molecule is not part of the coordination sphere, in which case it would be listed as H2O outside of the brackets.

Diaqua means there are two water molecules (H2O) in the coordination complex

Also, I would note that water is sometimes written as OH2 when in the brackets, because the oxygen of the water is what connects it to the central atom.

You can use this link when naming coordination compounds or find it on Lavelle's website

Would water outside the bracket ever be written in OH2 form?

Di aqua just means there are two molecules of water.

No you shouldn't. You write as OH2 to emphasize that at O it binds to the metal ion. The hydrate outside isn't asking as a ligand.
