Entropy will increases addition of heat and decreases with removal of heat?
Is this statement is right? if yes, why?

Irreversible means factors are not restored like heat. Hence for irreversible processes entropy increases.

Entropy is a property and for any cyclic process change in property becomes Zero doesn't matter if it's being carried reversibly or irreversibly.

The meaning of decreasing entropy is not means that it becomes less than zero. It may be remains greater than zero and also greater than 0.

Entropy is the disorder of anything.
For reversible cycle change in entropy is = 0.
For irreversible process change in entropy > 0.
If entropy < 0 then the process is impossible.
Nature always works in increasing entropy. Its linked to 2 nd law of thermodynamics as well.
