All are fine, except:
1, Jamie helped change toms bicycle tyre. ] tense ok, but should be "Tom's"
2. Future Continuous: Next week I have a music exam. ] Not quite. Would you like to try again?
3. She stopped to listen to the music] Not present perfect! Try again?
4. Dan’s been/gone to Germany ] Not past simple; try again!
5. Identify which syllable carries the main stress. ] I can't see the stress marked here.
Otherwise, well done!
(PS: You may find you get more responses if you post fewer questions in one post)
