Sets are too high. No need to go above 10 reps on any exercises really.
Keep the Arm exercise for now, at 10 reps, or if you can get away with a few more lbs on it, cut back to 8-9 reps.
Squats, down to 8-10 reps, so add more weight. I'd go initially for around 20% more weight, but no more. If you can tolerate that for 8-10 reps, then add a bit more each set, until either that or the next session, you'll find a happy medium.
The increased intensity might initially create more DOMS, (Delayed Onset Muscle Sorenes), which you'll feel within 36 hours of training, but after a few more sessions, if that happens it should start to dissipate and you'll feel it less.
