if we received a time pass up to 22 and we have a second test for free, can I sign up for it in advance? or will all the papers be handed out and written down at the airport?

You can go to the airport, it may be that you have already been automatically enrolled somewhere) you can overwrite by writing a letter to them in the mail)
