There's only one HAT in that list...
Will it fit to a zero? looks like it will.
Will it do so with that cae installed? No idea.
Will you need some sort of adapter to use the other two boards? Probably unles you're happy soldering wires to the underside of the board.
Can you use all three baords together? If there are no pin conflicts, probably.
One question? Given there is an accurate time signal encoded into the GPS signals why the RTC?
I'll ditch the RTC, is there a good way to have this particular GNSS HAT discipline the time on the Pi Zero W? For the MAX7219 displays I could use a GPIO stacking header like this one:

From what I can tell there are no pin conflicts other than that both need a 5V pin. The display I'm going with uses pin 2, 6, 19, 24 and 23 (it's a SPI interface). I'm quite sure that the stacking header I linked to can accommodate the GNSS HAT and leave room for connecting other peripherals.
Helpful answers are appreciated. I usually respond to Tweets directed at me. JWST is the Sagrada Família of spacecrafts. I code in Python on Windows 10 and Raspberry Pi OS.
