Will these lock strongly enough to hold backpack pins in place?

Yes they should have no problem holding pins in a backpack

what size pin back can I purchase to fit into these please and thankyou?

I’ve only used them on Disney pins. They are amazing and I haven’t lost a pin yet!

How do you remove them?

pull up on the circular top of the pin back to unlock it and then pull back to remove it. sometimes you have to pull a little hard or wiggle it to get it loose
