You are very welcome, Patrick :)

9, 10, and 11 are wrong.

Nirvana -- apparently you don't know the rules for this lesson. Please don't try to answer questions you don't know.

Very sorry :(

The "rule" is that, for example, "each student" is one person. Each is not a horde! Singular pronoun is used, as in "his or her".

The sentences you provided are correct. Here is how you determine the correct form of the pronoun in each sentence:

7. Both John and Jim said (he, they) were not exercising regularly.
- In this sentence, the subject is plural ("Both John and Jim"), so you should circle "they."

8. The jury was asked to return to (its, their) seats.
- In this sentence, the subject is singular ("The jury"), so you should circle "its."

9. Please remind each student to bring (his or her, their) homework tomorrow.
- In this sentence, you are referring to multiple students, so you should circle "their."

10. Neither John nor Bob was willing to admit that (he, they) had cheated.
- In this sentence, the subject is singular ("Neither John nor Bob"), so you should circle "he."

11. Each of the girls had (her, their) assignment completed.
- In this sentence, you are referring to each individual girl, so you should circle "her."

12. Every worker in this office needs (his or her, their) own computer.
- In this sentence, you are referring to each individual worker, so you should circle "his or her."

All of the circles match the correct forms of the pronouns in each sentence. Well done!
