That is a megaton of money Apple is laying out for these 7 movies, I’m guessing well past a billion. At these costs you need paying viewers, A LOT of them. Imho (just my opinion) not one would be a box office hit. Doesn’t mean they’ll be bad (or good) but nothing that’ll bring in 1.5x production cost.
If one does it’ll be Napoleon directed by Ridley Scott. The man knows his epic war-historical figure movie making.
