How many times a week or month is normal & healthy masturbation?. 2) when ever i masturbate i feel like a loss of energy i see in internet with post say that it nothing related to masturbation with loss of energy. but then why i feel like that ?

Use common sense: No special limit unless the masturbating is getting in the way of a person's ability to work or to eat healthy meals, is preventing adequate sleep at night, or is not allowing other exercise that all healthy people should be having. As always in life, one should do everything in moderation. Too much of a good thing... can be bad. One's mind and body does rest for a short while after each orgasm.
