Upon taxi in on Charley to spot 2 nearing spot 5 run up area; Aircraft X taxied onto Charley directly in front of us from South West Ramp. Aircraft X was very difficult to see as they only had nav lights on and were buried in the lights of aircraft doing run ups at spot 5. I saw Aircraft X pull onto Charley to [Runway] XXL with approximately 50 ft. or less to spare pulling onto Charley and took controls and immediately applied brakes to stop. Ground Controller issued taxi advisory immediately after I had stopped aircraft. I had all lights on during taxi at time of event.Crew could of done a better job listening to other aircraft taxi instructions to maintain better SA (Situation Awareness).
Instructor Pilot reported another aircraft entered the same taxiway resulting in emergency braking.
