Caylus 1303

Yes — once the first player passes, any later Worker placements cost an additional Worker returned to the Camp until you pass; the first player to pass takes the First Player tile (p.4). The Night Worker lets you keep placing Workers without paying that extra cost, and the Early Riser can place one extra Worker at the very start by returning one (pp.4, 8, 12).

Normally no — placing on an occupied Building is prohibited (p.4). The Journeyman is the exception: once per round you may place on an occupied Building and your effect resolves after the existing Worker; additionally, placing on another player's Building normally gives them +1 Prestige Point unless the Thief is used (pp.4, 8, 12).

During Activation, Buildings are resolved in order from the City Gate along the Road up to the Provost; any Worker placed on Buildings beyond the Provost is not activated and is returned to the Camp (pp.4–6). The Provost position (and players moving it via Toll/Guilds Bridge) determines which spaces are activated that round (p.5).

A delivered bundle must be three different resources and must include the meat resource, with each bundle worth 5 Prestige Points (p.6). The player who delivers the most bundles that round gains a Favor (ties go to the player who placed earliest), and some Characters (Deliveryman, Chamberlain) modify delivery rules (pp.6, 9, 12).

Yes — during Stewardship all starting Buildings above which you have a House flip to their Residence side automatically (p.7). Then, proceeding from the Guilds Bridge along the Road, each Residence owner may replace it with a Monument by paying its cost and immediately gains the Monument's Prestige Points (p.7).

Each Character has a specific timing: e.g., the Early Riser triggers at the very start of Planning, the Night Worker affects extra-placement costs after passing, Journeyman and Thief affect placement, Bailiff moves the Provost after Guilds Bridge, and Delivery-related Characters apply at Delivery; consult the character entries for precise timing and limits (pp.8–9, 12).
