1. give patty and her the prizes.

2. them invited my brother over to visit.

4. mary and me walked to the bus stop.

1. Give Patty and her the prizes. (the objective case pronoun her is used correctly to denote a person to whom the prize(s) should be given)

2. Them invited my brother over to visit.  (the subject should be They)

3. Will you and him climb Mt. McKinley with the Lees?  (the subject should be you and he)

4. Mary and me walked to the bus stop. (the subject should be Mary and I)
