Yes — when a production (stone) building is activated by anyone but its owner, the owner takes one resource cube (chosen among those produced) from the stock; if the owner activates it themself they take only the normal income and no extra cube is taken (page 3).

After players pay to move the provost (Phase 4), buildings are activated in order from the first space after the bridge up to the provost's current space; any workers on buildings beyond the provost are not activated and are returned to their owners without compensation (pages 3 and 5).

Yes — placing a worker on another player's building immediately gives the building's owner 1 prestige point; placing a worker on one of your own buildings costs 1 denier but does not give any prestige point to anyone (page 3).

If you placed a worker in the castle but cannot or will not provide the required batch (three different cubes, one must be food), you lose 2 prestige points (but not below zero); this penalty does not apply if you can't give a batch because the Towers section has no room left (pages 4–5).

Yes — the exclusive-use favor line lets you use construction-building effects even if the building isn't on the board (page 6); columns 3 and 4 of the favor table become available after the Dungeon count, and column 5 becomes available after the Walls count (page 6).
