If I am playing Shiotome Halls and Tadajai Sensei, do the honor gains 'stack' when destroying a province or army?
The Shiotome Halls After a battle's resolution ends, if a province or enemy army was destroyed during it and you control a unit in the winning army: You may gain Honor equal to the number of Battle Maidens in that army.
Tadaji Sensei After a battle's resolution ends, if a province or enemy army was destroyed during it and you control a unit in the winning army: You may gain Honor equal to the number of Battle Maidens in that army.
For Example: I attack with 4 Battle Maidens, destroying one card at battle resolution and destroying the province as well.
Do I gain 4, 8, 12, 16 or some other number of honor? Thanks!

Each card provides a separate triggered effect, so they will "stack."
In the example you provided, you would gain 4 Honor from each effect, for a total of 8 Honor.
Edit for clarification: The Rulebook will also award you 2 Honor for destroying one card in Resolution, assuming of course none of your Battle Maidens are dishonored.
