ok in the picture below there are
yellow plugs which are the plugs that you remove during a oil change. They they torque to 25 NM . The
red plugs which I think are the ones you pulled out by accident are galley plugs they also torque to 25 nm I believe they are pipe taper thread some type of thread sealant should be used but not necessarily a hard thread locker but I bet a medium grade Blue Loctite would work fine. The orange circles are the bolts people usually miss when pulling the sump pan.
Here is a shot from the manual
You can also see the old silver engine had the same plugs just different because of the oil galley locations on the design.
Hope this helps
