It seems like you've provided some direct speech sentences. If you want to convert them into reported speech (also known as indirect speech), here's how: 1. Trang asked what she should wear to the fancy dress party. 2. She wondered if she should help Chau with the money her mum gave to her. 3. Nick wondered where they could get those traditional handicrafts. 4. Phuc said that he was wondering who he could turn to for help with his homework now. 5. Hoa asked when she should break the sad news to him. In reported speech, we usually shift the tenses back. However, in these sentences, the situations are still relevant or not specific, so we can keep the present tense. Also, note that question words (what, where, who, when) remain the same in reported speech.
