I voted 5-6 but I’d forgotten about five more… Well, three if the ones outside don’t count.
We have:
A really tall one of Our Lord and His Sacred Heart (although it is all white, so it’s difficult to distinguish) outside by the playground and the parking lot.
One of the Blessed Mother in a grotto just outside the church, to one side of the entrance.
A medium-sized (actually, it’s more between medium and large), full-colour Crucified Lord complete with a kneeler in the vestibule.
A medium-sized, black-ish, grey-ish St. Peter at one of the aisle entrances.
A medium-sized, colour St. Augustine up on the ledge of the choir loft (does that description make sense?).
A medium-sized, colour statue of Our Lord in the same place as the St. Augustine but on the opposite side.
A large statue of Our Lady with a removable crown, to the side of the sanctuary, with candle trays and a blue background.
A large statue of the Archangel Michael victorious (titular saint of my parish), to the other side of the sanctuary, again with candle trays and a kneeler.
A medium-sized, golden-hued colour angel on each side of the tabernacle.
And of course, a really large, black-ish, grey-ish crucifix a reasonable height above the tabernacle.
So that’s 10.
Actually, there’s an 11th, but this seems like stretching it a bit… There’s one more of Our Lady on the roof above the main entrance to the school.
