So you really have 3 main pin sizes you will encounter in the hobby for pin tumbler locks:
For pin tumbler that covers most of what you will find, medeco uses 0.135 pins and some really small Yale locks use 0.095 diameter
So it sounds like you have a mix of American/Master locks and Abus which all happen to use 0.0925 size pins so you would be good to grab a pin kit for American/Masterlock

That’s a decent kit for about $50 that has good security pins that will work in ABUS/Master/American padlock, once you venture into loose cores or even different padlocks it can quickly get out of control trying to have pins available for everything you want to do so just be warned!
I know for a fact you can spend more that a couple thousand dollars acquiring all the pins you want as your collection grows, you just need to decide if you really need to repin locks or if you just want to make a couple CL along the way.
If you really are only interested in making some challenge locks I would suggest just spending a little cash on some 3mm brass rod and shape them to size as needed.
I thought I remember seeing a complete repinning set on here - I should have tagged it.
There’s this but I’m not sure if it has spring too -
