It seems as at one point every home, and many commercial/and even industrial buildings in Florida had jalousie windows. Yes, they're drafty. Yes, you can open them when it's raining for ventilation, unless it's a real 'blow.'
I agree the O.P.'s pic are awning windows. I didn't watch the video to see why the still pic shows awning windows, but it's titled 'jalousie.'
Properly cared-for, an awning window should provide decades of dependable service. The window cranks are probably the parts which need replacement most-frequently, from my experience. Locally, the big box stores in FL have the cranks. Ace Hardware also stocks them. For true jalousie windows, other parts may be more-difficult to come-by, like the stamped-Al clips holding individual jalousie slats. The tabs on those can be bent to more-securely hold the glass slats, as loose/broken/missing tabs on them may allow the glass to fall-out.
Awning window frames have a retaining screw on either side at the top of the glass frame for each individual pane, removal of these two screws for each window pane allows you to remove the individual Al frame/pane to take to the glass shop for getting a replacement. Do yourself a favor, and buy new retaining metal strips for the glass in the frame, removing the old glass retaining strips often bends them, making them not suitable for re-use. Often it's easier to just let the glazing shop do the pane replacement, and you're just removing/replacing the window frame.
The point on pivots where there are rivets needing a bit of free-play is something to remember if you're trying to do a pop-rivet repair. I've used the tip of a small screwdriver to get the needed spacing, though there's probably some special tool for this, which looks like a tack/brad-puller. A piece of thin sheetmetal with a notch cut-into it, and inserted between the pop rivet and the piece being riveted, and then removed after setting the poprivet would also work.
Mill-finish AL windows after years get oxidation which could interfere with operation, cleaning it and a bit of lubrication as mentioned helps restore proper function.
I will say that better windows will make a big difference in the comfort of the room where you have those awning windows, or where someone has jalousie windows. Yes, they're much-more expensive to get for-instance 'impact-rated' windows, or double-glazed or triple-glazed windows, perhaps argon-gas-filled. However the benefits of modern windows can make a room usable all four seasons, reduce heating/cooling bills, and significantly quiet the room from outside noise.
If you decide to look at alternatives for windows, I recommend CGI or PGT, both are owned by the same people. They are high-quality windows.
Not sure how a baseball bat would help. If some kids were using it to hit rocks or even play baseball insurance would pay for the repair? Even then it would just be repaired to existing condition.
