NTFS, fat32, exfat, could I theoretically create my own filesystem? If so would my computer even be able to work with most files or connect to other devices?

Yes. There are many different file systems and you can absolutely create your own. Making one that is reliable and performs well, and/or is something you can actually use for the disk that you boot from, generally involves low-level kernel programming and years of work - and is not exactly a beginner’s programming project.
However, you can also more easily play with implementing filesystems in a high-level language using FUSE.
Your computer can use many different filesystems at the same time. You can also store a filesystem in a file on another filesystem, rather than dedicating a partition of a physical disk to it. So, yes, you can use a filesystem of your own design at the same time you are using other storage devices formatted with more common filesystems.
