В скобках указан еще один правильный вариант, но менее литературный, более разговорный.

Мне кажется, что у Вас нет почти ни одного правильно написанного предложения.
Попробую написать правильно, насколько хватит терпения.
1 You're older than he.
2. You work harder than me (или I, почти всё равно)
3. Это предложение выглядит странновато, но пусть. Может быть. Только в конце he, а не his
4. Можно I, можно me. Оба варианта, в принципе, правильные.
5. Вместо them пишите they
6. ..more money than they.
7 ...faster than me
8. Лучше так: You has been longer here than she.
9. Здесь, вроде, нормально.
10. ..than he.

Так значительно правильнее.
