Answer 2

Jemi's (the guy/gal above me) got it down perfectly.
And as for the answer from the first poster, let me explain that the Japanese language does not have a word that ends with (when spelled out in alphabets) the letter "g".

Answer 3

Stop It!

Depends how strongly you want to say it. If you don't want to say it especially strongly, you can just say やめて！ (yamete), or you can add よ (yo) to the end of it to sound a little more annoyed. If you're being serious or scolding, you can say やめなさい！ (yamenasai).

Help!
Same rules. 助けて！ (tasukete). Or, to be polite, 助けてください！ (tasukete kudasai).

She's attacking me!
彼女が襲ってます！ (kanojo ga osottemasu)

Good job!
There are a variety of ways to say this. One is 頑張ったね！(ganbatta ne). Literally translated, this means something like "you got your strength together (for it) didn't you?" To be more polite, you can say 頑張りましたね。 (ganbarimashita ne)
There's also よく出来たね！(yoku dekita ne). 出来る means "can" or "be able to", so "you were able to do it very well, weren't you?"　よく出来ましたね！ (yoku dekimashita ne)
There are a million other ways to EXPRESS this, but Japanese people just don't say "good job", so these two are probably the closest.

We are Beautiful
Depends if it's a man or woman saying it, and depends on how polite you want to be.
Casual, a male: 俺たちが美しい。(oretachi ga utsukushii)
Casual, a female: あたしたちが美しい。 (atashitachi ga utsukushii)
Polite, a male: 僕たちが美しいです。 (bokutachi ga utsukushii desu).
Polite, a female: 私たちが美しいです。 (watashitachi ga utsukushii desu)

My Japanese is not that good.
Again, depends on if the speaker is male, or female, and how polite you want to be. "My" can be 俺の(ore no)、僕の(boku no)、あたしの(atashi no)、私の(watashi no)。
So "[My]日本語がまだまだです。(nihongo ga mada mada desu.) Mada mada means "not yet" or "not up to par" or "not there yet."

Wow!

すごい！(sugoi)

It's so cute!

"cute" is simply かわいい(kawaii). "So" can be 超 (chou)、めっちゃ (meccha)、 or すごく (sugoku), your choice.

Bye.
If you don't think you will meet again, you say　さよなら。(sayonara)
If you do, you can say またね (mata ne) or じゃあね(jaa ne)

Hope to see you again.
Japanese don't say this, so don't worry about it.
