Answer

Thank very good teacher Austin very much for very careful, reasonable and detailed explanation.
It is very kind of you to help me.
I would rather help you to learn Chinese than learn English if you would like to learn Chinese( due to a native Chinese speaker)

Answer

All three of sentences 1 are correct and natural. In my opinion sentences 1(a) sounds that best, but others my have different opinions.

Sentence 2 all sounds a bit unnatural to me because usually a person wouldn't look three times before stopping laughing. But grammatically, you could write them as follows:

2(a). Three looks at his face and Jane stopped laughing.
2(b). After three looks at his face, Jane stopped laughing.
2(c).  Jane stopped laughing when seeing his face three times.
2(d).  Jane did not stop laughing until she saw his face three times.

I would probably write it as 2(a)
