Difficult o say for sure due to the poor image, but it IS likely that the inner tooth on that right mandible has broken off.
It is likely to have been bitten off by another stag, as there are bite marks on the mandible which were probably caused during a fight, yes.
It is quite common to find damaged lucanids, particularly where they are in high densities and or many species coexist.

They're all living organisms, not manufacturing by machines. You can't expect every single specimen to be perfect.  |

They look like battle scars to me. They fight all the time and it's perfectly normal to have battle scars on them.

Not broken, try running your finger on it if it feels smooth then it's probably not broken, if it feels sharp then it's probably been broken off.
Yes the little holes and scratches are the " battle scars"

I quite often get Prosopocoilus torresensis and Cacostomus squamosus here in Australia at the light with broken- totally snapped off one mandible.
You can clearly see the broken sharp edge under a micro scope or hand lens.
Also there is a lot of mandible variation within species and it is easy to see that.
look carefully and it will be obvious.
