Sry to hear that you struggle. But Im not sure what exactly you struggle with so I guess its the Input? Thats because Pawns have a 1to1 Controller relation.
But there are multiple ways to overcome that Problem. You can give you Copys a fake AI Controller that Mimics your Inputs. You can Attach your Actors to your Original and the will keep a relative Offset so you have to manage just the Animations. Or you keep refferences of your Copys and send the Input directly trough a custom event that hooks into the same Movement Logic (assuming you dont use Controller for Movement)
Also Consider using Actors instead of Pawns it comes with downsides and upsides.
If you need a example that does not use Multiple Pawns there is a Astroids Template on the Forums from Elhoussine Mehnik its for 4.7 but the general basics should still apply.
