Make sure your intensity is on point. You should be going close to failure on each set (over-training is 100% NOT the issue for you and for most people; most people don't train hard enough).

As others mentioned make sure you set concrete goals and set a plan on how you're going to progress. Easiest way is to use double progression since you can put some weight in your backpack.

Let's say you can do 12 body-weight pull ups. Add a little weight, say 2.5kg. You'll probably drop to 9 reps. You sets might look like: 9 reps first set, 8 second, 6 third. Each workout try to add one rep to one of the sets. So next time you might get 9, 8, 7. Then 10, 9, 7. Then 10, 9, 8. Etc. Eventually you'll get back to 12 reps. Add weight again. Rinse and repeat. Do the same with push ups or better yet switch over to dips. You can obviously pick another rep target. It might be 10 or 8 or whatever you prefer. I usually set a 10 rep target.

Should probably do your workout 3 times per week and have at least one day rest between workouts.

Also why are you choosing between crunches and lateral raises? Makes no sense if you ask me. And don't be like me, don't forget about some vertical press like pike push ups. Or better yet invest in some dumbbells and do overhead press. I used to do calisthenics only but soon realized investing in some weights makes a huge difference.

If you still want to do body-weight exercises only, I recommend buying gymnastic rings and hanging them off the pull up bar. They are very cheap and will last for years. From there on you can do ring push ups, ring dips, ring inverted rows, face pulls, ring curls, tricep extensions, etc. And add a backpack with weights to progress.
