You can get location, level, alliance, class, and character name from the guild list or friends list functions.

From API page on wiki:

     GetFriendInfo(luaindex friendIndex)
        Returns: string displayName, string note, integer playerStatus, integer secsSinceLogoff 

    GetFriendCharacterInfo(luaindex friendIndex)
        Returns: bool hasCharacter, string characterName, string zoneName, integer classType, integer alliance, integer level, integer veteranRank 

     GetGuildMemberInfo(integer guildId, luaindex memberIndex)
        Returns: string name, string note, luaindex rankIndex, integer playerStatus, integer secsSinceLogoff 

    GetGuildMemberCharacterInfo(integer guildId, luaindex memberIndex)

They operate on an index, so you have to iterate through the list to find a player with certain name.
