Although I can't think of any specific examples, I would say, for #3, look towards the villains who know Batman's secret identity: Ra's al Ghul, Bane, Hugo Strange, etc.

For a more recent example, maybe Batman: Death of the Family? I mean, Alfred did get captured and tortured by the Joker because of Bruce's "connections" to Batman.
