All of those will work, including the Mopar. The only difference with the Rebel is the fender flares are black plastic instead of painted, the size is the same so all mud flaps for 1500 with flares will fit fine.
Personally I would get the Husky flaps. They are longer than both WeatherTech and Mopar for better protection and honestly think they are the best looking for the Rebel. They also don't ride up on the fender flare as much, reducing the chance of scuffing up the flare. They also have the most basic and secure mounting setup.
Note I only installed the fronts to help prevent rock chips thrown from the front tire hitting the rear quarter. I also now have the factory running boards to aid in rock protection, works great with the Husky flaps.
