How do you difite lorelei and Bruno Agatha?

It seems you're asking to differentiate between Lorelei, Bruno, and Agatha. However, there isn't enough context to understand who or what these names refer to.

To help me differentiate them, please provide some more information:

* What are they? Are they characters from a book, movie, TV show, game, or something else?

* What do you want to know about them? Are you looking for their personality traits, their roles in the story, their relationships to each other, or something else?

Once I have more context, I can help you understand the differences between Lorelei, Bruno, and Agatha.
