First of all some clarification.
The image above is the "Navigation Pane" of Windows "File Explorer".
The "Quick Access" menu above contains only "Desktop" "Documents" and "Pictures"
The items you have highlighted in yellow are outside the "Quick Access" menu.
To get rid of "Libraries" simply right click a blank area of the navigation pane and untick "Show Libraries"
Save it, extract all, use the "Individual Folders" container within the 32 or 64 bit subfolder (as per your system architecture) to "remove" and or "restore" the folders as you require.
You can highlight with control for multiple files and then right click mouse and hit delete. That is in file explorer and Quick Access being the recently viewed files. I wouldn't mess with Onedrive especially if you don't use it. It's highly integrated into Windows 10.
