Uncredited English voice cast

The only end credits I could find: https://www.youtube.com/watch?v=a74LDdQZVrI&t=1h23m15s show the following:

1. Amano - Christopher Courage
2. Akemi - Rebel Joy
3. Nagumo - Danny Bush
4. Megumi - Lucy Morales
5. Kuroko - Rose Palmer
6. Myuni Hausen - Bick Baise
7. Takeaki - Jake La Can

What sources do we have for the other names? For example Barbie O'Buoy supposedly doing the "Feris" wheel victim?
