I would leave them, I have had eggs with mold before and still go full term. IMO there is only one egg that looks iffy.
If you can separate the one moldy egg from them rest without damaging the eggs you may be okay. Then again like I said they may all go full term with no problems.
You can use a soft cloth and try to wipe the surface mold off and see if that helps.
You only have a week left and then you can cut them to see how they are. Just remember to keep them moist with water until they come out of the egg.
