What tools do I need to build a wireless camera system that transmits data via radio or something like it (not Wi-Fi) to a display, like a 1.8" TFT screen? I want to use a small camera, such as the ESP32-CAM, and connect a transmitter, like the NRF24L01. The controller could be an Arduino Nano, ESP8266, or ESP32, while the receiver will also be one of these three controllers connected to the 1.8" TFT display. The output could be something between 2 - 5 fps (or more if possible but those are my requirements) What hardware do I need for this project, and what about the code in general?
Why not? It's usually the best option.
Because I need it to be on a TFT screen or oled, not a phone screen or something like that.
You realise the range of WiFi and NRF24L01 are very similar? They share the same frequency band and have a similar transmit power.
I don't care about the range (I just want the range to be between 3-5 metters), I just don't want to enter the wifi and its password. If there was an option similar to it without the need for wifi.
Do you think WiFi is somehow incompatible with TFT or OLED?
Most phone screens are TFT or OLED.
I think you need to do more research before you decide "I want this" and "I don't want that" because your reasons are not making much sense at the moment.
Have you considered Raspberry Pi Zero W? Maybe you could use one for the camera and another for the screen.

Have you done the study to show that this can be done? Especially using a NRF24L01 with a 32 maximum record size?
Why I'm i getting humiliated 
I meant that how do you do it WITHOUT THE NEED OF A COMPUTER SUCH AS A MOBILE PHONE.
I know using an nrf24l01 is impossible I'm just giving out example for the radio modules.
This is what you want

I want to do it for the fun of it.
I'm not, nor ever will be, "bruh" Why are you so rude?
Ok im very sorry. (english is my 2nd language)
That is fine. Use a translator or standard English. I use the translator often.
Not trying to humiliate anyone. Just explaining why the "reasons" you are giving may not be valid and trying to understand your true requirements.
Shouting will not help. Calm down please.
I'm pretty sure a Pi Zero W can set up it's own Access Point. The second Pi can be given the credentials so it can connect. There's a wide range of camera modules with different capabilities that can be connected to the Pi's camera connector.
Many TFT modules are available with HDMI inputs that could connect to the second Pi.
You can display images from an ESP32CAM on a remote TFT.
320x240 images or smaller is OK. There is software that can cut the images down in halves, so 640x480 to 320x240 etc. The TFT does not display the images that quickly however.
That was with an ESP32CAM and a ESP32S3 as the receiver and LoRa UHF radios. Not tried it yet but the code should work with the 2.4Ghz LoRa modules that can be run at 1300Kbps.
Quite doable
Do you have any examples such as code examples or images?
So ESPnow is not acceptable?
It all done for you
It does not use WiFi, no IP or passwords, very simple.
