Generally; that partition table is a mess, the easy way to get rid of such mess is to take backup and then clean out the disk entirely, then reinstall the one OS you wish to use.

Little key icon shows mounted, so you need to use live installer with gparted or a gparted ISO. You seem to have multiple "New Volumes", you know backup on same drive is barely a backup as when (not if) drive fails or user makes mistake all data could be erased. Better to have another drive.
