I can connect the iMac 2012 with the iMac 2015 so surely there must be a way to connect them both to the Macbook Pro at the same time?!
iMac 27″, macOS 12.6
Review the document: Use your iMac as a display with target display mode - Apple Support
Target display mode is a feature available with late 2009-Mid 2014 iMacs. The display Mac has to be running macOS High Sierra or older and the signal producing Mac has to be running macOS Catalina (ca. 2019) or earlier.
Your new MBP will have an OS version that is too new.

Is it possible to connect a Macbook Pro 2023 with both an iMac 2012 and iMac late 2015? ie to have two screens connect to the laptop
