Can you take a laptop in your hand luggage on the plane?

Yes, that's allowed. You can even use it. I've already done that often.

Is it broken in the plane? Because I'm really scared to put it in the suitcase because people like to throw their suitcases around so brutally when they're being transported.

You can carry the hand luggage and do it under the seat. Then nothing is broken

Regarding the rabidness you are completely right. I've seen it with my own eyes several times as they pepper the suitcases back and forth. That's why I would ALWAYS do something like a laptop in my hand.

the question "is it broken there", I do not understand. You alone are responsible for your hand luggage. If you treat it gently, nothing is broken.

Yes, you just have to unpack it just like the mobile phone at the security checkpoint

Yes, you can also take two or three. 😜
