2. Is your chinese character handwriting good?
a. 我寫的中國字好看。

Both of them are correct. They might sound a bit long in daily conversations. Think what your answer to the question would be in English. I would simply answer "Good". :D

3. Are you able to sing alot?
a. 我會的唱歌不很多。

revised:我會唱的歌不多。

不很多 is acceptable in spoken language. However, I personally would not recommend it.

唱歌 is a verb with a noun, which literally means to sing a song/songs. Thus it is not correct after the verb 會的.

You may choose to take out the verb 唱 and simplify it into 我會的歌不多.

4. Do your parents like the things you bought? 

a. 東西的買我父母不喜歡。

revised:我(的)父母不喜歡我買的東西。both formal and informal. It becomes more informal when the 的 in the bracket is omitted.

You may occasionally hear some people say 我買的東西我父母不喜歡. That is quite informal and colloquial, and not uncommon in daily conservations. Again, I would not recommend this.

5. What is your favorite Taiwanese food called?
a. 我最喜歡的台灣菜的叫餃子。？

revised: 我最喜歡的臺灣菜是/叫餃子。

The second 的 is not necessary here. Either 是 or 叫 works here. You can pick one. I would prefer 是.

In my understanding, the traditional chinese version of 台湾 should be 臺灣。I am not expert in this, but I suggest sticking to one way of writing.

6. Do many Americans like to study chinese?
a. 想學中文的美國人不很多。

Please refer to the previous 不很多

7. ? Are americans able to speak many foreign languages?
a. 會說外國文的美國人不很多。

revised: 會說外語的美國人不多。

I am not sure if 外國文 is commonly used in overseas Chinese communnities, like in Singapore, Indonesia. But in mainland, the most proper word here should be 外語, which works both in written and spoken Chinese. 外文 would be good too, but a bit too formal and relatively rare in daily conversations.

8. Do people who like to read books often buy books?
a. 喜歡看書的人常常買書。

9. Do American women make their own clothes?
a. 做衣服的美國小姐不多。

revisied: 美國女性很少自己做衣服。or 自己做衣服的美國女性很少/不多。

The word 小姐 is kind of tricky these days, due to its recent implication. There are some other words for women in Chinese, but they sound either too formal or too informal to me.

10. Are people who are able to speak chinese also able to XXX chinese?
a. 會說中文的人都會XXX中文。

revised: this XXX must be teaching. Its pronunciation is jiao1.
