I’m not sure what you’re asking here. Any Sonos “room” can group with any other. Choose Five, One etc for your other rooms depending on your budget, size of room, and what sounds good to you. 

Thnx. So ones or fives. Will work fine?  I’m new to Sonos. 

Or Arc if you need another home theatre setup… or Amp if you have existing speakers you want to re-use. Or Move or Roam on wifi… Sonos is a multi-room system which enables synchronised music play across multiple speaker sets/rooms. There is a (32?) limit to the number of speakers, but that’s about it. And rooms can be grouped on the fly to suit where you need the same music playing, but of course can be playing other music in rooms outside that group.
