Dips and chin ups incorporated into a workout?

To all that answer my questions I thank you so very much in advance for taking your time. I am presently following a exercise program that incorporates working out my body parts over 4 days during the week. My back and biceps are done on Monday, and my chest and triceps are done on Tues. This is followed 6 days per week for one hour a day with cardio, and a high protein low carb diet( good carbs, oatmeal, rye, wheat, fruits and veggies) with no refined nothing and only water.This program has helped me lose almost 20 pounds and still going strong. And since muscle burns fat faster than fat burns itself, I want to develop my weak areas, like my arms and back. Now my questions are as follows. I know using isometrics( body weight) does build you up like in the military. When should I do dips( for my triceps) and chin ups( close and long) for my back and biceps? Since I directly work these body parts only once per week, it is enough to do chin ups and dips only once per week? I want to do as many times per week as possible. In the military they do them everyday, can I do them everyday? Since my ulimate goal is to lose another 30 pounds and p the entrance to the military and get through boot camp. Will this hurt my development? Doing dips and chin ups will they help me when I do my bench press and curls? Will the dips help me with pushups? How many dips and chin ups should( reps ) I do, and how many sets. I presently do three sets and max( until failure). Also when it is not possible to use weights(not available or gym busy) and it is my time to do triceps or biceps, can I just do dips and chinups? Any and all help would be greatly appreciated.
