They all seem to be related to system or preinstalled apps, so at least we don't have to be worried about malware. Unfortunately, I don't have a Note8, so I can't compare directly. On my Pixel 2 XL, I have 72 folders, many of which start with "com.", and are related either to apps I installed or preexisting Google apps.
Did all of those folders get created after you had owned the phone for a while? Or did you just recently get the phone?
Also, you didn't do any hacks to enable Adoptable Storage, right?
