I wonder if it would endanger the plane. A 20g explosive sitting in the pocket of a person will clearly cause serious injury, but I am unsure if it has penetration power to actually go through the plane body. I am reminded of mythbusters experiments with small amount of explosives to block up doors, but I don't recall how much they needed in the end.
In some of the cases you mentioned, there were passenger deaths due to being ejected from the aircraft. I'm on mobile or I'd link exactly which incidents but I remember at least two cases from when I was bored in a lecture and read through most of Wikipedia's "list of deaths in aircraft incidents" list or whatever it's called
Yes, there are passenger deaths from some of those incidents. But the plane wasn't brought down.

These are all fake news. According to Hollywood, a single bullet from a gun will cause an airplane to break apart in mid-air. You can't honestly expect me to believe Hollywood movies get physics wrong.
Similarly, as soon as a car's wheels leave the ground, it bursts into a fireball according to many TV shows I've seen.

Naturally the close quarters will results in multiple people being harmed. The question is more about the physics and if the explosives has enough penetrating power to go through the walls of the plane.
The bigger risk to the plane (and passengers) would likely be if the person carrying the explosive was working in the airport and the explosion occurred during a critical moment, like when a pilot is taxiing.
Poking holes in the fuselage of a jetliner isn't going to take down a plane. Consider the cases of a turbine fan blade taking out a window, the case where the MAX door panel blew off, the cases where the cargo door came off, and the 737 "convertible" case. You'd have to take out a large part of the structure to bring it down.
Take a look at all the photos of B-17s taking severe combat damage yet returning home. Jetliners are a lot more redundant today than the B-17s were.
However, if the hole took out the flight controls, or set a fire, then the airplane has a big problem.
