Santiago is definitely Chaotic Neutral - he has little regard for the hierarchy, is mostly working towards his own ends and tends to be a bit unorthodox in achieving them
Juan is Chaotic Good - He strives to see whatever realm he is in prosper and grow, but also tries to ensure that the freedom granted to all levels of the realm are protected.
Carlos is a bit difficult. He cares little for the games and wars of the realms, save that everyones behaviour is honourable. Course he only really considers his definition of honourable, but that is hardly a rare thing. Probably Lawful Neutral
