No. You may perform the entrance action, the Path of Tea action, or both once each, using possibly different Geishas. Entering the Tea Garden costs 2 coins, while advancing costs 2 or 5 Chasen for 1 or 2 steps (p. 7).

No. A movement of 1 or 2 steps must be paid and completed by one Geisha all at once. Once a Geisha leaves the entrance toward the Tea House or Pond Overlook, she cannot change direction (p. 7).

The Pond Overlook can hold only 1 Geisha from each Clan. Each Tea House room can hold at most 2 Geishas from the same Clan (p. 7; p. 8).

No. The green-line option is specifically an additional placement option for a green die, following the normal placement rules. The other Domain icon does not activate the green die line; it refers only to white, coral, and black dice (p. 6).
