My project need to connect IR receiver & sender, 315MHz & 433MHz receiver, ext eeprom and a tft touch screen, but after I connect the screen, only 3 pin left, any idea? thank!

You can use a I2C 8-bit IO expander IC to control your CS, D/C and maybe T_IRQ signals. It may also be used for the IR receiver (depending on the datarate) and IR sender (if your sender actually generates the 38kHz carrier itself). Your eeprom may also use I2C so it will share the I2C bus with the port expander.
However, since you haven't mentioned how your IR and RF modules are controlled and used, we cannot really help any better...
It is also important to know if modules are used concurrent and how frequent...

Or step up to an ESP-32, which will give you more GPIO's, Bluetooth, dual core, 240MHz, etc...

How about using GPIO1 and GPIO3? They can be detached from the UART.
