What is the personal information of Ponyboy and Johnny?

Ponyboy is an interesting character, in many ways because
his emergence at the end of the story as a quietly confident young man has more to do
with him figuring out who he really is than being toughened up through his rough
interactions, the more commonly written technique for someone's growth.  One of the
reasons he is such an interesting character is that the interactions as part of the gang
are really a sideline to his personal development, not the main
story.

Johnny, on the other hand, is a character whose
manner and actions are determined almost entirely by his interactions with and
particularly the beating he received at the hands of the Socs.  Johnny has an
understanding of some of the things that Ponyboy feels but that understanding is the
result of externalities rather than internalities.
