I thought valves at first, but only because theres 8, but in reality a copper washer on a valve won't last long.
The other 4 look like they may be for banjo union possibly? But the shaped one on its own and the silver ones I have no clue.
banjo washers 8,,,,,4 injector bottom washers,,,,,,2 ally spill pipe washers and a sump washer me thinks
not all injector washers are lipped! 8 banjo washers on 4 banjo bolts 2 on filter head 2 on fip pump spill pipe to filter head maybe,,
yeah I've a box full ,,,,save them for later but they never fit owt ,lol
