No. Vestigial organs are organs that were previously useful to an animal, but, even though they are no longer useful, remain because evolution hasn't taken them away yet. Seals still use flippers.
yes
If you are referring to the system of borrowing and unification: Virtually all of them. Only the very earliest cinema organs did not use this system - they were simply church style organs set up in a theater - not to imply that church organs do not use borrowing and unification but at the time the key action of organs had not developed enough to use this system.

Because they had no organs!
Pipe organs have different sized pipes because they can then make different sounds.

All living things have and use organs just like humans. They may have more or less than us but they still have and use organs.

One of the characteristics of the theater organ is the tremulant. Also, whilst the prevalent stop on a church pipe organ is the Diapason or Principal, on the theater organ it is the Tibia Clausa, a pure flute tone. Theater organs also have stops not commonly found on church organs such as the Kinura and Post Horn. The strings are usually quite a bit keener and louder as well as typified by the typical Wurlitzer Viol de Orchestra. One commonality is the Vox Humana. However the voicing of theater organs is usually quite different than church organs, particularly if the church organ in question was built after the Organ Reform Movement. A Church organ built during the romantic or orchestral period may make a fairly good imitation of a theater organ simply by turning on the tremulants. However the tremulants of theater organs are usually quite a bit faster and deeper than church organ tremulants. The best bet is to make maximum use of the strings, trems and reeds. Do not be afraid to use the mutations as well. Don't forget that theater organs were highly unified so that many stops played at every conceivable pitch.
