How do you correlate which version of Gnome Desktop does a certain version of Ubuntu ship with?

How do you most reliably and accurately correlate which version of Gnome Desktop does a certain version of Ubuntu ship with, without going through installing that version of Ubuntu? I’m relating here to more recent versions of Ubuntu, e.g. 18.04 and up.

Either what version comes with the base version of Ubuntu, or, any patch version that comes with the official updates for that version of Ubuntu.

How can I install more than one Desktop Environment in my Ubuntu without damaging the system?

How can I install more than one Desktop Environment in my Ubuntu without damaging the system? I want just to try those desktop. I know I can install them by sudo apt install kubuntu/xubuntu/lubuntu-desktop . But it will remove my existing Desktop Environment, right? I want that whenever I want to change the Desktop Environment, I will log out and log in to that. Is it possible to do that? Don’t say to download ISO image of Kubuntu, Xubuntu, Lubuntu as I want to see them in my current installation.
