Fan hub/controller mean kinda the same thing, except sometimes people say one is more advanced than the other. They are (usually small) devices where you can connect multiple fan to, to control them all at once.

RGB controllers are the same thing, except for RGB colors, instead of fan speeds. Of course you have to look out for what brand of RGB stuff (fans, strips, etc.) you get and if they work together at all with each other.

An external USB Hub takes 1 USB port from your PC and splits it up so you can connect more than 1 device to it. Internal USB Hubs are very similar, except for inside your PC. Inside your PC you have USB headers (USB 2.0, 3.0 and 3.1 Gen 2 ones) and they are used to connect a variety of devices including the USB ports on the front of your PC, but nowadays also 'RGB devices' and fan hubs (such as before mentioned RGB/fan controllers, many all in one liquid coolers with RGB too) to control your devices' fan speed or color. When you don't have enough internal ports for all this stuff, you get an internal USB Hub.

RGB fans are two separate things in one package: RGB lights, and fan.

 

Fan hub: Controls fan speed

 

Pins: 4pin fan = PWM. 4pin RGB = light control. Read the manual.

 

RGB sync controllers : controls lighting effects

 

USB hubs: I assume you mean those that comes with RGB fans or strips? Those are used to connect to the PC itself through the internal USB 2.0 headers, the same ones meant for front I/O. They give you a hub just in case you need more USB headers than what the motherboard has.
