Not as in "reaction" but as in "to act again."
Example sentence:

I tried searching re-act on the Internet. But I only got react.

1 : to enact (something, such as a law) again
2 : to act or perform again
3 : to repeat the actions of (an earlier event or incident)
Yes, re-act is spelled with a hyphen specifically to avoid confusion with react and it means
To act, do, or perform a second time.
The Oxford English Dictionary calls it a "rare" word. Nevertheless, it has an example usage from the Times (London) from 2007:
If you owned both a green carpet and a stripey cat, you could re-act classic scenes from Life On Earth in your own home.
So, feel free to use it. In context, it should be clear what it means.
You can use replay as in:
One could limit the scene to 8 lines of dialog per player. Then ask the players to replay the scene
No, re-act can't be used like that.
You can use "repeat", as "He wanted to repeat his part of the script." (possibly ambiguous) Another possiblity is "redo".
Or you can use a rephrasing:
He wanted perform his scene again.
He wanted a second take. (In the context of video)
