Thank Aamer, you're right, I should focus on learning English first but it's so exciting to be able to speak several languages. Maybe when I am at a more advanced level of English, I can practice Portuguese a bit, for me that language should be easier than the English language.

I have same feeling as you, it makes me jealous to meet someone who speaks several languages but I still learning English and still need to improve it before moving to another language, but actually I have started to learn new language but it was a big distraction for me, actually it depends on how long free time you have, so if you only have about one hour ber day for studying new language then you better focus on English, but if you have more time then it would be ok if you start something new. This is just my opinion
