This looks like a case for wireless whole house audio. Sonos would be the "obvious" example solution, using an Sonos Amp for each location.
The drawback for Sonos is the relatively high price. There are other ecosystems, and I'd suggest looking into DTS Play-Fi.
Onkyo/Pioneer receivers have Play-Fi built-in and there are inexpensive streaming receiver options such as the Phorus PR5 that you could attach to any receiver or a separate amplifier.
Other inexpensive streaming receiver options are Amazon Echo Dots, Chromecast Audio, Dayton Audio WBA31, etc.
Other AV receiver ecosystems include Denon Heos and Yamaha MusicCast. some Sony models also include Chromecast.
Some can transmit what comes in from an analog input to other devices in the ecosystem.
You could keep your surround system separate in this case, which may make the total solution less expensive.
If you do use an AV receiver for all the speakers, and you try to put multiple speakers on the same terminals, you have to be careful on the effective impedance of the speaker set. If it's too low, you can draw too much current, which could make the receiver fail. Wiring in series vs parallel may help resolve this.
You may find other options in the Home A/V Distribution forum

I just moved into a house and there are 2 speakers in the ceiling of 3 rooms. I would like to wire these up to a receiver I think so I can steam music from phone. I want to be able to play in room 1, 2 or 3 and also a combination. Would like to control this from my phone without needing to press buttons on the receiver. Looking for advice on best receiver options…. I might also want to link in sound from the tv and be able to play sound from movies in room 1 only. Hoping to get some guidance on here - many thanks in advance
Total 6 speakers so 12 wires… was thinking of putting 2 wires into each output for same room so maybe I don’t need as many channels. Heard this can be bad for the amp..
