"Please come back before it got dark."
"I will come back before it got dark"
Are these sentences correct ? Can we use future tense with unreal past ?

Sorry. Those are both wrong. You need before it gets dark in both cases.

What about the sentence "I am glad I came back before it got dark" ?

This sentence can mean that the speaker came back before it got dark sometime back in the past and he is glad.
But if someone comes back before dark and says this sentence even before it is dark, would it be correct ?

Yes. The sentence is correct in that case as well. Grammatically, you are just matching tenses. "came" and "got". The meaning is clear.
