Entropy will remain constant as it point function and here the process is cyclic.

Entropy for the irreversible system may remain greater than zero or may be less than zero. Entropy depends on internal irreversibility as well as external irreversibility.

How to easily understand the reversible (Carnot cycle), irreversible and entropy process?

As per the Clausius Theorem and Inequality:
The net changes in entropy in one complete cycle attributes a zero entropy change to the most efficient engine cycle.

Entropy can never be > zero.
Change in entropy can be < 0.
Change in entropy can be < 0.

Entropy is a system property. So cyclic integral of entropy is zero. Thus entrpoy of the system does not change.
But the entropy of the universe should obviously increase as it is irreversible process.

For a cyclic process entropy change is always less than or equal to zero.

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.
