The 2 on the right aren't allowed because your abbey -which is considered as a cloister- would be adjacent to 2 shrines, which is not allowed according to the CAR.
Shrines are placed and scored in the same way as a cloister.255 However, a shrine may not
be placed in such a way that it adjoins several cloisters.256 Similarly, a cloister may not be
placed so that it neighbors several shrines
The one one the left bottom, i think is the same...if you put your abbey there, then the shrine is surrounded by 2 cloisters...
