My sealed bottom bracket (square) is moving a little bit so I want to remove it to see if changing it is necessary.
The bottom bracket I use is Right/left thread (First is the brand. Shimano compatible) and I want to ask for help before trying to remove it since I am a bit confused about turning clockwise or counter-clockwise.
Mi bottom bracket looks like the first image below.
If I want to remove it from the drive side (side with chain), should I turn to the right or left? What else should I do? Should I remove it from the drive side or from the opposite?
The right side of the bottom bracket is reverse threaded. Therefore, you will need to turn it clockwise to remove it. It is probably gonna be extremely tight so be careful not to mess anything up, or take it to your LBS.
I removed the left side of the bottom bracket by turning it counter-clockwise but when trying to remove the right side (driving side) clockwise, I can't move it. It is extremely hard. Is there a trick to be able to remove that side. It's frustrating getting to this point and then stop.

The only recommendation that I have for you is to take it to your LBS and let them remove it. They should have a special t-handle spanner to remove this.
It is possible to kill your frame if you foul up the removal of a BB cup. If it isn't going with reasonable torque, take it straight to the LBS. Normally, the fixed cup goes quite loose when the adjustable cup is taken off or loosened. I wonder if the movement that you've noticed has mashed the thread a little or a lot. Just check that you don't have an Italian threaded BB - is the frame Italian?
