1. He is an early bird.

2. He is a morning person.
(Are both the same in meaing, right?)

3. She is a late bird.
4. She is an evening person.
5. She is a night person.
(What about these sentences? Can they be the opposite of #1 or #2? Do you have some other expressions?)

1 could mean simply that he is early getting to school or work, whether he wants to or not! 2 definitely means he functions much better in the mornings than later in the day.

In place of 3, I'd write "She is a night owl." 4 and 5 are fine!
