♠ - What are they afraid of?
Failure. He's afraid to let whatever happened in the past, happen to him again. Though he doesn't really own a successful circus right now (it's not even really a circus), he's still afraid that everyone would walk away again. But what he's most afraid of? If children would lose their interest in him, or when he's unable to cheer them up and make them laugh. It's all he's aiming for in life, and if that ever slips away, he surely would have nothing left.
♦ - What is one thing about them that they are most proud of?
The fact that Joachim was willing to give him the title of Ringmaster! To Ludwig, it was a dream coming true. Of course he felt sad at that time as well, as he learnt about the reason behind it, but that still didn't wash away the pride he felt. He had become the leader and owner of his favorite circus, and that truly brought him joy, and confidence as well. In fact, he wanted to rub it into his father's face that he had come this far, if he didn't hate and feared his father that much.
