I searched a couple topics but nothing really clarified. I have a few books but cant really narrow down the address in NEC. Is the GEC at Service disconnect need to be on same buss as neutral or equipment frame? I recently ran service call at a multi family dwelling I noticed a common GEC wire tied to each service disconnect with mechanical lug per disconnect

Yes, each service disconnect would require connection to the GES. I would have used non reversible crimps.

It must terminate to the neutral if the MBJ is a screw or bonding strap. If the MBJ is a wire or bus type then the GEC can terminate to the EGC bus/frame.
It may or may not be code compliant you would need to provide more details. There is a GEC connection with a lug at each service disconnect but what's on the other end of the GEC?

The GEC can be connected from the POA on down to the SE. Most want it at the SE disconnect.
Each disconnect frame has a mechanical lug and the #6 runs through Each no slices. The ground rod has an acorn clamp
Can you provide address in NEC that mentions if screw or strap it goes to neutral bar
