By this, I assume you think the inside of _one_ LS in the following questions.

I think so inside an LS, at least as the current working hypothesis.

Yes, in the same sense as above.

I do not know how photons behave, but at least light propagates with speed c
_as a wave_ associated to photons. This does not prevent instantaneous forces
inside an LS.

I am not sure enough, but at least by my working hypothesis any particles do
not follow Minkowskian structure if considered inside an LS.
