How can I find the current sigs?

Hi, I wanted to ask how I can get the sigs myself. If someone could help me with that it would be really nice.

I need the following:
FreeFn
UWorld
LineOfS
GetNameByIndex
BoneMatrix

With best regards

uWorld: 0x9865730
LineOfSightTo: 0xcf2a999
FortniteFree: 0x995d19c
GObjects: 0x968c240
GNames: 0x48c30264

No that's not how I wanted it to be. I need them like this:
48 8B 05? ? ? ? 4D 8B C2

And it would also be good to know how to get them myself, so I ask.
