1. Jenny has to do her homework after school. В данном случае глагол have в 3 лице и единственном числе переходит в has

2. Tom must walk his dog every day. Здесь есть указатель every day, значит, нужно использовать Present Simple. То есть просто walk, без окончания -s, потому что есть must

3. Could you pass me the sault, please? Здесь не нужна частица to.

4. He needn't go to school on sunday. После need, should, must, could  и тд глагол идет в Present Simple.

5. Should we buy a ticket? Do здесь не нужно, ведь есть уже should.

6. You must not park there. Как я уже упоминал, после must идет глагол в Present Simple.

7. She hasn't to go working every day. Здесь в значении "идти работать" - go working.
