I'm a bit fuzzy on the power of Hojatsu Sensei because of the plurality.
Interrupt, w: Challenges created by the action and issued by your Personality with a Weapon bow the other Personality after he loses the duel or refuses the challenge.
Do I target a Personality when he issues a duel and then any time he issues a duel that turn it will have the added effect of the bowing? Or is it a one off? The part where it says Challenges (plural) makes me wonder.

Into the Wastes (Event) Timing question' Engage: You have the first opportunity in this battle to pass or take a Battle action, which must come from a card in a unit.
If my opponent is attacking me and I have this event ready to go but then he uses sneak attack. If I then pop it does my action take precedence over his since I acted last? Also while I'm here Defender always acts first by default correct? Even in engage. (This is no doubt in the rulebook somewhere)

I couldn't find them in the rule book. Do they stay in play the rest of the game until I replace them?

Interrupts are only taken to interrupt another action, and (generally) all effects of an Interrupt will refer only to that action: Hojatsu Sensei only effects challenges created by the action it interrupts. Note that it doesn't require you to target anyone, it just checks whether the Personality issuing such a challenge has a weapon. Note also that an action can create more than one challenge, for example Heroic Sacrifice.
If more than one Engage action attempts to change who gets the first opportunity to act in the Combat Segment, only the last such effect will be applied. Your Into the Wastes will trump your opponent's earlier Sneak Attack - although he could play another Sneak Attack and regain the first opportunity.
As described on p8 of the Reference Rules, the Defender has the first opportunity to act in the Engage Segment.
Katas have no special rules. Cards which enter play generally stay in play until some effect removes them from play. The only rulebook effect which does this is the "Discard Terrains" step at the end of a battle, where Strategy cards (Terrains and, in Legacy, Formations) in play at the battlefield at discarded. Katas, however, enter play in your home, so they are not affected.
