Different ways of saying "shut up" and "be quiet" in Japanse
Both romaji and kanji/kana, if you please! Arigato gozaimasu!And also if you could tell me which is better with who and in what context, which one is more polite and so on... I rely on you, my Japanese friends :)

Answer

Apart from the answers already posted, another common one is:

Urusai! 　　　　　　うるさい！

All of these are pretty informal。。。　a more formal one would be　Shizuka ni shite kudasai (please be quiet) 静かにしてください

Answer

Your way of question here is in detail and good ! :)

---impolite----  definitely arrogant and selfish ...to make your surrounding calm with this sentence.
*喧しい（やかましい）! 
うるさい！
 * 黙れ!
(damare!)

---between impolite and polite----  sometimes It is used in both polite and impolite case . It depends on accent and situation.
静かに。

----polite----
静かにしてください  because ~してください　means "please" in this sentence.

Good luck :]]]
