The ones that might need more correction are the first 2 sentences. You might want to put "xibuxihuan (do you like)" and "huibuhui (do you) " before the activity, which is listening to music (ting yinyue) and play sports (da yundong). Just like the ones you did with 3-5.
The other ones seems fine. But if you would like to make the pinyin even better, you might want to correct some of the tones. When two words have the same 3rd tone (V), you can change the first one into 2nd tone (/). For example, in "ni you", both are 3rd tones, as in sentence 5. You can change the "ni" into second tone. When we read it out loud, it sounds a lot more natural.
And for the content, all sentences makes sense and they're understandable.
