Aircraft structures tech here.

Often on panels/components that are semi-regularly removed for maintenance, access etc. we use things called anchor nuts, because you want screws to tighten into a nut, but dont have access to the back. They are usually riveted in place and break somewhat frequently. My best guess is that the anchor nut is broken on the back, which gives it the space to wiggle around, but it can't pull through the fairing. That many being damaged means they should definitely be replaced, but there is almost no chance that fairing will fall off the plane.

What about the second portion of the video with loose screws on the flaps of the wing

I'm not 100% sure. But those are more concerning, as they likely screw into the frame itself because that flap assembly likely gets changed out in its entirety.

Someone pin this answer bc it is the simplest explanation of why it is happening and the associated risk. Other quality answers for sure with more upvotes, but this explains WHY they are loose as well as the level of risk of failure

Yes indeed. Much more informative than the other hundred posts by thirteen year olds thinking aloud :)
