How do the Socs act and what is their gang code. How do the Greasers act and how do they stick together?

In my opinion, both of these gangs have a similar code. 
Their code is that they stick together and protect one another from anything that is not
part of their gang.  They both serve as family for their
members.

You can say that the Socs act more aggressively
than the Greasers.  They seem to be the ones who go out looking for trouble.  But this
may just be because it is a Greaser who is telling the story.  Clearly, the Socs try to
protect each other, like when a group of them wants to fight Pony because he was
involved in killing Bob.

The Greasers also stick together
and protect each other.  You can see examples in the time that they save Pony from the
Socs and when Dally helps Pony and Johnny get away after they kill
Bob.
