OBD II normally list them for Bank 1 and Bank 2 since these are controlled by the 02 sensors. Never saw an engine data listing fuel trim for each cylinder since each cylinder are not controlled by an 02 sensor.
If the Fuel trim was negative that means the 02 sensor will be taking away gas from the mixture (Rich Condition). The injector will close sooner.
If the fuel trim was positive that means the 02 sensor will be adding gas to the mixture (Lean Condition) The injector will stay open longer.
From the Data your engine appears to be running cool. That could cause the DME to send a signal to the injectors to provide a richer mixture since cold engine needs a rich mixture.
