I didn't get the charger, I have a couple of chargers lying around, do any of them work?
Maybe. Impossible to say without knowing the specs of what you have.
A well regulated 5v PSU capable of at least 3A should work but will restrict current to bus powered USB devices. A PD capable PSU with a 5A@5V mode will not.
A non USB PD supply will also restrict current in the same way regardless of how much current it is rated for.
TL;DR: buy the official PSU. It's the only way to be sure.
[edit]
All of my comments regarding current limiting and USB PD apply to Pi5 and 500 only. Earlier models do not support USB PD.
