I'm a geographer, not an astronomer, so there's your grain of salt.
If all you need is the hour angle, then you could just substitute the moon for the sun in this equation you posted here:
How do I calculate solar altitude and hour angle from the surface of another planet?
...But as you've posted here:
https://astronomy.stackexchange.com/questions/25352/how-do-i-calculate-the-hour-angle-of-a-planets-moon-from-a-point-on-that-planet
what you're really after is
a standing stone calendar that'll accurately denote where to look for my planet's moon at its four major phases
And that's not something the hour angle can tell you. The tl;dr is that
your full moons will not be in the same places every month;
the hour angle seems to only give you you degrees longitude;
and you'll also need a predictor of latitude to tell where they are.
The long version is that this is due to a combination of two reasons.
First of all...
You have exactly 20 lunar months for one solar year (640.04 days around the sun / 32.002 days around the planet). You're going to have exactly twenty new moons, twenty full moons, etc throughout your year. And that's fine.
You also have 768.68804 solar hours per lunar month (24.02 times 32.002).
This is also fine, but that .68804 is important. I'll get back to it near the end.
Secondly...
More importantly, your moon's orbital inclination is 9.92 degrees off the ecliptic in relation to a planet whose axial tilt is 14.92 degrees (for reference, our moon has an inclination of 5.145 degrees in relation to Earth's 23.5 degree axial tilt). And that's also fine.
So, assuming your planet and moon have the same dimensions as Earth and our Moon, here's a not-to-scale diagram of what your system will look like if we assume your moon reaches its highest latitude in the northern sky on the same day as the northern summer solstice.
And here's a closeup of your planet on that hypothetical day. The upper red line denotes the highest northern latitude that will, from their perspective, see the moon as directly overhead.
Now, let's both flip the planet and reflect the moon's orbital inclination 9.92 degrees below the pink line so that your moon reaches its highest latitude in the southern sky during the southern summer solstice. In this case, it's the lower red line that is the highest southern latitude that will see the moon as directly overhead.
By these powers combined...
The result of these two things is that your moon is going to create a sinusoidal path, like the ones described here:

Because of the .68804 hours (which is about 41 minutes, 19 seconds) each apogee and perigee of your moon will occur not quite 10 degrees, 15 minutes of longitude away from the previous one. This creates the overlapping wave pattern in the video posted above.
And that sinusoidal path means that all twenty of your full moons will rise at different latitudes on the horizon between those two red lines over the course of the year, similar to how the sun rises at different points between the Tropics of Cancer and Capricorn over the course of a year here on Earth.
This isn't to say that you can't make your calendar. But to the best of my knowledge, the sin waves used in the equation for hour angles describe the longitudinal motion of a celestial body over a planet, and you'll need something to describe the latitudinal motion as well.
