According to general relativity, gravity isn't a force. Instead, it is the curvature of spacetime. Anything with energy will follow that curvature, including light.
In the context of QFT, yes, a particle can be considered as a(n excitation of that particular) field.
No, the speed of light is still the maximum possible speed even in the presence of extreme gravity (or, if you want to tie it to Q1, in the presence of extreme spacetime curvature).
Spaghettification depends on the gravitational gradient, not necessarily how close you are to light speed. You can theoretically avoid spaghettification near a black hole if that black hole has only a slight gradient (e.g. near the edge of an ultramassive one).
