I do the Portuguese once, I do the Portuguese twice:

1. But I don't have sixteen - mas eu não tenho dezesseis
2. sixteen - dezesseis
3. seventeen - dezessete
4. eighteen - dezoito
5. and two cost sixteen reals - e duas custam dezesseis reais.
6. they cost - custam
7. I am buying one - eu compro uma
8. And you are buying one - e você compra uma
9. I can buy the beers - Eu posso comprar as cervejas
10. You drink one - você bebe uma
11. And I drink one - e eu bebo uma
12. And 11:15 - as onze e quinze
13. At 12:00 - o meio dia (the half day)
14. No, now - não agora
15. Not now - agora não
16. Nineteen - dezenove
17. But not at a quarter past nine - Mas não a nove e quinze
18. At a quarter to eight - As quinze para as oito (that is what I am hearing, not sure if correct)
19. At what time do you eat - A que horas você come?
20. You don't eat much - você não come muito
21. You don't eat well - você não come bem

Bonus: This is one I put together all by myself. Have to know how old the garotas are, after all!

How old are you? - quantos anos você tem? (Hope that is correct, I just adapted the Spanish version "cuantos anos tienes tu?")

Anos in Spanish means asses.

Ok, ok. So I was too lazy to put in the ñ. Besides, isn't it more fun to ask a girl how many asses she has?
