Hello I’ve got 4 Arduino UNO’s and a Raspberry Pi 3 B+. Is it possible to connect multiple Arduino’s using the HC-05 module to the Pi at the same time and have them all send data? Because all the tutorials and resources online I’ve seen only show one.

And for good reason. That is the way they are supposed to be used. I'm sure Raspberry Pi can use NRF24 modules, and you would be better off making a network with them.
It is possible to have what at best is a quasi network with HC-05s, but it is tedious, and only for the desperate. It involves sequentially reconfiguring one-to-one bluetooth connections under software control. "At the same time" is indeed a relative term, but separate one-to-one bluetooth connections is really in another arena.
