Red light appeared 3 separate times in 20 min

Looking out over the ocean, we saw a bright light appear low over the horizon. At first glance it looked like a star, but it quickly faded then started moving from left to right. After about 10 min, in the spot where the light stopped a red light appeared, brightened until it was very bright and clear, then faded away to almost nothing. It was only bright and red for 2-3 seconds. Within 10 min this same light brightened and turned red in another spot nearby, fading just as quickly. Within 10 min of this sighting, it appeared a 3rd timed but this time it multiplied into 4-5 red lights. It looked like a firework with how quickly the lights appeared, they stayed very close together, in a circle or maybe semi-circle, then just faded away together again after about 3-4 seconds. There were no trails or movement, the light didn’t scatter, they just faded away again.
