Inking is a once-per-turn turn action by default, but effects can allow you to put additional cards into your inkwell or put cards directly into the inkwell without counting toward the once-per-turn limit (see 4.2.1–4.2.3, page 12).

No — triggered abilities are added to the bag when their condition is met and then resolve later following the bag’s resolution order or when the current effect finishes (see 6.2.3, page 30; and bag resolution, pages 39–40).

No — an activated ability on a character that has an [Ink] cost can only be used if the character is dry, which requires it to have been in play since the start of its controller’s turn (see 6.3.1.1 and the Set step, page 31 and page 11).

Damage in a challenge is calculated for each character and then all damage is dealt simultaneously (place damage counters equal to the damage dealt), after which a game state check occurs (see 4.6.6.1–4.6.6.3, page 15).

Drying means a character can’t quest, challenge, or pay ink costs with [Ink] until it has been in play since the start of its controller’s turn; characters stop drying during the Set step of that controller’s Start‑of‑Turn Phase (see 1.7.5 and 3.2.2.1, pages 6 and 11).

Self‑replacement effects are applied first, then the player whose cards/effects are being affected chooses among other applicable replacement effects, and you repeat the process for any modified event until no more replacements apply (see 6.5.6–6.5.7, pages 33–34).
