Hi Helder. 

Yes, there are often a lot of words in English that mean similar things and can be used interchangeably.   To learn which words we use in everyday English you need to listen to Native English Speakers and read a lot.  Listen to movies, TV, podcasts, or anything that is of interest to you. Do it for enjoyment, not because you have to do it:)   Read books, articles, newspapers,  blogs or anything that you find enjoyable.   You can find lots of English newspapers online and most have videos with them as well.  

By reading and listening you will learn the current words we use.   You may notice however that certain words may be used more in one country or in one area of the media more than another.  

Also speak with Native English speakers as much as you can:)
