Here are some other ways to say "no" depending on the context:
* "Não, obrigado/a" (No, thank you) - This is a polite way to decline something.
* "De maneira nenhuma" (No way) - This is a stronger and more emphatic way to say "no."
* "Não quero" (I don't want) - This is a more direct way to say "no" and is often used when refusing something.
* "Nem pensar" (Not even thinking about it) - This is a very informal way to say "no" and is often used when refusing something strongly.
It's important to note that Portuguese has a few different dialects, so the pronunciation of "não" may vary slightly depending on the region.
