Once you have a Contact instance, you simply have to run the following code to 
update its nickname.
Updating other fields is trivial, please let me know if it works for you:

// assume your contact entry is populated
Contact entry;

entry.ContactEntry.Nickname = "newnick";
ContactEntry updated = entry.ContactEntry.Update();

According to your screenshot you are getting a 412 Precondition Failed error, 
which means that you are trying to update an outdated entry:

http://code.google.com/intl/it/apis/contacts/docs/2.0/developers_guide_java.html
#Updating

After you call Update() on an entry you have to use the returned object for all 
following updates. To be clear, your code in the try block should look like:

entry.Emails.Add(new GExtensions.EMail("skyfei2@Gmail.Com", 
GExtensions.ContactsRelationships.IsOther));
GDataContacts.ContactEntry updated = entry.ContactEntry.Update();
updated.Nickname = "Nickname";
updated = updated.Update(); // reusing the same instance for future updates
