From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Oh I just watched a video about home. So is that a partition of it's own? the guy was saying he was using different homes for each distro and it became a mess, so he planned to install one home directory for all distros.... idk?
/home is a directory ("folder"). Inside that directory, there's one subdirectory for each user, where you're expected to keep your personal files, configuration files, user data from software (e.g. save games from your games), stuff like this, personal data.
And Linux allows you to mount any partition in any directory of your choice.
Because of those two things, a lot of people create a partition and mount it as /home. So if something bad happens with the distro, and you need to reinstall it, ~~your princess is in another castle~~ your data is in another partition, safely stored. It's usually a good idea, but in your case it's a bad idea - because your /home/[insert username] directory from one distro will be likely the same as in the other distros, so they'll interfere on each other, and software user data will become a mess.
Instead, what I recommend you is to not create a /home partition. Let each distro have its own /home. However, do create a partition to store your data, and mount it inside your /home/[insert your username] directory. That way you can access all your files from all your distros, but the software user data won't be mixed.
Ahh brilliant! so create ONE storage partition and just mount that one partition in each distro's home directory?
Yup. Check the diagram that I posted as a reply to another comment. It's a clean way and it allows you to access your files from all your distros.
At least in theory you could even use a /home partition if you really, really wanted, but then you'd need to make sure that your username is different for each distro. It's more work than it's worth, and muscle memory will make you to try to log into one system with the username of another system.
