You can add sub-forums to a sub-forum to as great a depth as you wish, so it is easy to create any number of "mini-forums".
I am not sure if I understand the next part of your question. If you want your own icons beside your sub-forums "Noticias", "Debates", "Sugerencias", etc, then you have to edit the NAML code that creates your forum. I believe that the macro you would need to edit is "topics_column", but I am not expert enough to tell you haw to do that.
