Five Red lights moving in strange patterns

At first it was just one big red light and it wasn't moving. I thought it was a bright planet, so I took out my nightsky app and it was not showing up. So I keep looking at it, trying ti figure it out. And then four more appeared. They all lined up from left to right in a diagonal formation, and then they started moving around up and down and seemed to be forming patterns. This went on for about 15-20 mins. I fortunately found a neighbor at the very end, who at the end saw just the one bright red light and he watched it go poof...just disappeared. The other red lights all traveled to a spot in the sky, and one by one they disappeared into that location.
