Hero of the Sky is pretty simple. At the end of Chapter 8, there is an optional map リブリィール山脈. You must clear that map before moving on to Chapter 9.

Amdusias is a more complicated process, and requires you to make certain story choices in Chapters 6 and 7. She is only available for part of Chapter 7 and again at the beginning of the Final Chapter. I don't remember the exact process anymore, but I used these sources when I played the game a while back.
