Here are some other ways to express "no", depending on the context:
* "Não, obrigado/a" (No, thank you) - This is a polite way to decline something.
* "De jeito nenhum" (Absolutely not) - This is a stronger way to say "no" and is often used to emphasize your disagreement.
* "Nem pensar" (Not even thinking about it) - This is another strong way to say "no", usually used to express a firm refusal.
* "Não quero" (I don't want to) - This is a more informal way to say "no".
Remember that the specific expression you choose will depend on the context and the level of formality of the situation.
