Note: I have little belly fat and my lower outer chest joining armpit is saggy and nipple area is flabby but seems getting reduced with my workouts. My hair is also falling and kind of small patches created thats why I increased diet.However I need advice to get firm chest and flat abs with Lean fit body.

Thats pretty detailed information. However, before starting or making any workout routine, one should have precise goals to achieve. I am not sure what you want to achieve here, but the kind of routine you are following will help you to reduce fat and help you to increasing muscle strength. Essentially you are including 5 exercises daily along with 20 min running, so I guess weight control is target here but with 71 KG at 5'9", you are just at right spot.

Your another is issue is hair loss, for that increasing diet won't help, sometimes it can even harm you, like if a guy is taking too much egg white protein then can experience hair loss. However, in your case, you said you have small spot of hair loss in scalp, it looks like you have Alopecia areata, I suggest you to meet dermatologist as soon as possible as he can only give you right advice.

For saggy nipple, it depends what kind of fat deposition you have, it could be onset of gynecomastia but as said, can only be said after physical examination, however if you were obsese then too you can have saggy chest after loosing weight. I suggest you to now shift to muscle gaining routine instead of weight loss and make sure you are not over eating, that way you won't see such sagginess if muscle starts building up along with fat loss.
