6 and 7. If you squint and lean on a bit of confirmation bias, photo 9 looks like a commercial airliner with the Alaska Airlines livery.

Without context, it does appear to be a quadcopter-ish shape, but since the caption says the object was at high altitude, it fits a regular airplane well.
People live on site watching the object move should certainly know better. (Perhaps they do know, and are intentionally trolling.)
Be careful here. Human eye witnesses are not reliable, especially at night like this. It is very hard to determine size of shapes at night in the dark. It is hard to determine distance which makes something small look like it might be bigger but further away.
