For the rusty pieces only.....
Soak pieces in solution of 50% white vinegar and 50% water for couple hours. Now this will depend on each piece, BUT remember vinegar is an acid and acids EAT metal You will ruin your piece if you let it in the bath too long. This is NOT like a lye bath.
Remove from vinegar solution, rinse and rub/brush to determine if rust has been removed. Repeat vinegar bath if required.
Dry, oil, wipe, buff.
The others look like a good wash and then seasoning them is all that is needed.
