Can you wire two thermostats to the same furnace

Possibly yes but why would you want to do that. One will override the other only sometimes depending upon the settings. Not worth the effort and it can possibly damage the furnace or the equipment unless some safety steps are taken.

Please explain what has to be controlled (the applications) and why.
Just placing thermostates in series for different rooms will leave you with a lot of temp problems all around.

Do you try to arrange for some form of different temps for different rooms?

Just follow up on this...
