Hi,
Yes, the terminal commands I tried didn't help.
I saved a couple terminal outputs:
Terminal output 1:

About the names of the folder(s), I have changed their names while the have been in trash.
This begin when I deleted one user account from my MBP. It went successfully (no error codes etc.), but after the process I noticed that in the folder Users there was still one folder from the deleted account (I noticed later that inside that folder was another folder etc.). I moved it to trash but wasn't able to empty the it (got those error codes). Then I tried to move that folder out from trash to desktop, but instead of moving the folder Finder made a copy of it to desktop. I moved that back to trash and voilà - I had two orders in trash i couldn't delete.
Below is a a link to screenshot of my trash, as it is now. Strange that many of them look like the have been modified today. I haven't touched them. Thank you for your help!
