At least 10 UFO sighted over Carmel, Indiana

On October 26, 2014, two friends have noted about ten luminous dots in the sky with different colors above Carmel, a city located in Hamilton County, Indiana. What is it?

Witness report:

I was helping a friend put up a sign right across the street from Maggiano's restaurant located in the fashion Mall area. I was holding the ladder for my friend when I looked to the sky and saw a bright dot. When I looked closer I counted 10 dots. All different colors. Looked to be solid and headed in the direction of the sun. I saw this for about 5 minutes until it was out of sight. My friend at the time saw this as well.
