The coil sleeves on all the coils in the photos look like they need some serious cleaning.
I suggest you install new coil sleeves on all coils and clean the plungers.
Check associated moving parts to make sure they are OK and clean/replace as necessary.
A flipper rebuild kit will have everything that you need in one package, but there is a significant price difference for all the parts.
Check all the diodes on those coils while you do that and replace as necessary.
Coil sleeves and diodes are cheap and will likely make things work better.
