If you have an electron and an observer,if the observer accelerates does the electron emit photon?

 

No. Acceleration is not relative. If the observer accelerates, then we know it is the observer who accelerated.

If you have an electron in a vacuum chamber onboard a space ship,if the space ship accelerates does the electron radiate energy?

 

Yes, though what happens depends on the details of what's happening with the electron. If it started at rest, absent any forces on it, it will remain stationary as the ship accelerates. Eventually it wills slam into the wall of the vacuum chamber, which would cause it to radiate. If it was accelerating along with the spaceship, it would radiate.

Are all particles considered to be an excitation on the same field?

Or is there an electron field for electrons,a positron field for positrons

a photon field for photons,a gluon field for gluons etc?

 

With energy being transferred from one field to another?

The latter. You can just think of different particles as being excitations in different fields, and those fields can interact with each other according to some rules we call "laws of physics."
