Yes, controllers can be mixed and matched depending on the setup.

The main idea is clear. Mixing controllers and different brands or types when playing PC games—especially Rocket League—doesn't require buying new ones. You can borrow from friends: 2 PS3 controllers, 1 Xbox 360 controller, and 1 PS4 controller could all function together in a split-screen setup.
It seems like you're asking about installation requirements. Could you clarify if you need information on drivers, special programs, or a plug-and-play setup?
Yes for PS3, DS3tool works. For PS4, Steam games don’t support it, but non-Steam options exist. DS4tool is available for Xbox controllers—do you need to confirm that?
I believe a dongle is required to link the 360 controller to your PC, though Windows may already have built-in drivers for the Xbox controller. For PS3/4, Bluetooth is an option if you prefer wireless use, so a Bluetooth receiver on your computer would be necessary. Regarding PlayStation controllers, I think Steam provides built-in drivers in the big picture mode (especially for PS4), but if not, SCPtoolkit can be used.
I owned an Xbox 360 before and connected two PS3 controllers via MotionInjoy, a tool to use PS controllers on Windows. My friends played FIFA with great smoothness. Everything was wired.
