Zero11 is a A6M5 Model 52 and has tail number "8-36" with a kanji "岡" (Oka) above it.
Zero12 is another Model 52 with tail marking "61-131".
The video reveals that Zero13 has tail marking "8-03" with the kanji "千" (Sen or Chi). Yet another Model 52.
At the end of the video we can see the following aircraft in the hangar.
It's not a Zero but a Nakajima B5N2 "Kate" tail marking "KEB-306" with radar.
At some point the "Kate" was pushed out of the hangar and was loaded on a trailer to be shipped to the U.S.A.
