I found the name of the second one:
Mariposa fueguera Mechanitis lysimnia
I couldn't find the name of the first one yet.
It is not the best time of the year to see butterflies here (Winter) . But the North is hot almost all the year long and I could see some beautiful ones. Unfortunately I could not take pictures of a really beautiful one that was flying around.
This one :
