Yes you can - they install by default into separate directories. I have installed in Windows the final version of every stable release from 2.6, and the current (and one other) development version so that I can compile and update any lilypond code I come across. Frescobaldi has them all linked in so the correct one is used automatically.

Can I keep an operational 2.22.2 while I attempt to download and install 2.24.2? Depends on the installation method. With a package manager on Linux or macOS, usually no, but if you're just downloading the official binaries from lilypond.org, then yes, no problem at all.
