In a Chevy Camaro, like most V-shaped engines, the cylinders (and therefore pistons) are numbered sequentially from the front of the engine, starting on one side of the V and then continuing on the other. However, there's no single "front" as it depends on the orientation of the engine in the car.
To know the precise numbering, you need to look at the engine itself. A diagram on the engine or a service manual specific to the year and model of the Camaro will show the correct numbering scheme. There's no universal answer without that specific information.
