I plan to have a display (4-Wire SPI TFT LCD Display Module 240x320) connected to a Pi Zero:

I know that to connect the display I need to wire the screen to the Pi like so:

Display--------Raspberry Pi

BL--------------pin 12 (GPIO 18)

SCK------------pin 23 (GPIO 11)

MISO----------pin 21 (GPIO 9)

MOSI----------pin 19 (GPIO 10)

CS--------------pin 24 (GPIO 8)

RST------------pin 22 (GPIO 25)

D/C-------------pin 18 (GPIO 24)

VIN-------------pin 17 (3.3v)

GND-----------pin 20 (GND)

I also plan to connect two of these:

But as you can see, some wires from the screen and the gamepad pcb use the same GPIO pins? How can I connect both to the Pi?

I didn't check your wiring diagram to see if it's correct. The answer about connecting two wires, though, is this: Connect them via a breadboard or proto-board in lines that are connected inside the board or splice the wires together somewhere away from the board.

I see you're using stuff from Adafruit. You can get a breadboard from there (among many other places). If you're soldering pieces, their particular form of protoboard is called "perma-proto breadboard."
