No, you should not be worried about supernovas. While they are powerful explosions of dying stars, they are typically far enough away from Earth to pose any direct threat to us.
Supernovas are the explosions of large stars in space.
No, they are much smaller.
The explosions of supernovas
A supernova is a star saying "The End". The H-R diagram shows they different types of stars by spectral class, color, etc. It was never intended to show the ending of stars. On most H-R diagrams, you will find at the top, or occasionally top right, a place for "Supergiants". Some of those stars will eventually become supernovas. To be absolutely clear: A supernova isn't a type of star - it is the "end" of a type of star.
Supernovas release a wide range of electromagnetic radiation, including visible light, X-rays, and radio waves. This emission is a result of the intense energy and heat created during the explosion of a star.

No, you should not be worried. It is fine.
Does the friend has the history of stealing. If he does then you should be worried, but if he does not you should not be worried. But to be safe, you can keep you stuff on safe place to avoid excuses.
no
Stars do not create supernovas. Supernovas happen to stars. A supernova is when a star, bigger than our own sun, explodes due to the lack of gas they need.
Yes, you should be worried if it was not caused by mosquitoes or falliing.
Star Dust from supernovas is what makes technically 'everything' in the Universe.
They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.
should i be worried about this bump at the corner of my right ears?
In space.
Depends if you want to be pregnant. If not you should be worried...
The most dangerous type of radiation is Nuclear radiation which is the one that should be most worried about.
