How could i unlocked the teams that there is a '?' sign on them?

If I understand your question right, all you have to do is to win the different cups (International Cup, Euro Cup, America Cup etc.)

yeah... you understood... but i won all the cups in the game and there are still 3-4 teams that are locked

You have to win the corresponding continental cup with each team that has a classic counterpart.

So, for example, you have to win the European cup with England, Netherlands, Germany, etc. if you want to unlock each of their classic teams. Just winning the European cup once doesn't do it.
