Apple Tree Leaf Problem Diagnosis

Hi everyone! Since this was my first year with trees in the ground, I am still learning to diagnose the various diseases/pests I had with my apple trees. I’ve got two Honeycrisp and one Golden Delicious. I know I had some scab and cedar apple rust. But this picture definitely shows some various problems I dealt with. There’s even a little green caterpillar worm right on the leaf! The grey spots at the bottom would all end up becoming holes all the way through the leaf (see the top left hole). I also had leaves where it looked like layers had been eaten away (see the very top). Can you all help me with what else might be going on? I want to be prepared for next season!
