Temporary profiles are an issue that can happen, it's been a "thing" since as long as Windows NT has existed, so like 35 years so far. If it's working now, you can clean up the folders.
#temporary user bug

Often when you get logged into a temporary account (profile loading failure), the solution is often to create a new working account, move your files/apps there, then delete the broken one. But since you said yours is working after restarting a few times, that's probably not necessary
I personally like to create an alternate user account on my computer for "emergencies". It's an account that's not linked to any online service like Microsoft or even OneDrive or the app store, it's just a plain admin-level local user account that I can use if ever needed.
the built-in admin account is disabled by default and while it CAN be used that way, I recommend keeping it disabled and creating your own admin-level user account for such things.
But anyway, the error you see is indeed the "expected error" when the profile can't load properly and when you're about to get dumped into a temp one
yes you sure can. It's super unlikely that there's any data you want in there unless you created a file while logged in there, although to be super safe you might want to just send these to the recycle bin and then wait for a while until you're sure you want to empty the trash
that ought to be plenty of space! I bet these are really tiny
yeah
virtually nothing inside by a registry file almost
I wish I could say what may have caused you get thrown into a temp profile but glad it's working again
