GC - Can CL kindly post loadPlayers / loadFriends - array details

I am trying to make sense of the GC sample code and documentation but there seems to be few things missing in the docs. Can someone from CL kindly comment?

playerID - returns string values that look like this : G:123456789

alias - is not in the documentation - but seems to exist (as per sample code) and seems to return what GC calls Nickname. Correct?

Real Name - GC reveals this either to everyone or to friends depending on the GC setting. Currently I can’t see this in the documents or the sample source code.

Any way to get Real Name in loadPlayers / loadFriends? Thanks for your consideration.
