I don't see any limit on using multiple Planar Bindings. Given that each binding will last up to a week and a half, and if one is so inclined to make use of the spell with proper preparations (Magic Circles, Dimensional Anchors, calling diagrams) to begin with, I'm seeing a 12th level Sorcerer using this spell in multiples to easily have a dozen or so Glabrezus ready in a week's time for his next outing. And probably 9 or so Vrocks available for an hour/day after that. All available by RAW, see where this is heading....

I'm seeing you do that and upset everybody at the table who then all have to wait over an hour for you to finish your round.
However, having multiple planar bindings isn't entirely a bad idea. I like having them stay off-stage as options when you need them (you never want to show people all your cards).

Well the rest of the party is involved, at least for the 1st binding, in case of that rolled 1 Cha check. After the first day of binding, they can go to the tavern or bounce around town to gather information.
I'd propose some kind of limit on binding spells. What would be fair? Perhaps 1/day, due to the strenuous/careful nature of the casting? It would still allow multiples over time.
