Yes, but the actual hangar deck is relatively narrow. You can look at exterior pictures all you like, but it doesn't change design of the set. Now, the hangar set is, apparently, a fairly typical segment. It's got two pairs of launch tubes, with a launch control room in between them. Behind each of two of these tubes is a neat little space happens to perfectly fit a Viper. There's a double-wide behind another tube and the launch control room where you could fit two vipers. The fourth is taken up by the toolroom. So, at an absolute minimum, assuming every segment is identical, and that there isn't more hangar extending past the launch tubes, that means that there are 40 Viper parking spaces in a single pod. Taking a more rational view, that there's only one tool room per hangar segment (eight launch tubes bordered on each side by an aircraft elevator, or two iterations of the set), and that the there are another two hangar segments (one on each end) with no launch tubes (doubling their storage capacity), then we get up to 81 viper parking spaces. So, that's fairly comfortable, space-wise.
But let's go nuts! After all, there's that big main drag of the hangar bay, where they do the work and keep the Raptors and move Vipers in and out of the tubes and on and off of the aircraft elevators. It's just wide enough you could have a Viper in ready position, just behind the tube but not all the way back into its parking space. So, filling it until you can't fill it no more, the Galactica's port flight pod could hold another 66 Vipers, bringing us to a grand total of 147 Vipers per flight pod, or 294 for a fully functional battlestar. I'd like to reiterate that movement would be severely restricted, both for personnel and for craft, and there is no room at all in this loadout for Raptors and shuttles. Or, for that matter, forklifts, pallets of poorly-secured communications drones, captured Cylon raiders, and whatever other things populate the hangar deck.
Now, giving people and planes enough room to move around, and enough free floor space for a few shuttles and twenty-odd raptors, I think an upper limit of eighty vipers per pod on a Galactica-type battlestar is more than reasonable.
