It's a big improvement. It's well organized. It's quite readable. I have a few suggestions for revisions.

The love-scenes (Christy’s relationship with Pegeen) contribute(s) considerably to Christy’s change of character.

Use the singular (contribute).

Just like the classical way, the opening dialogue serves as an introduction to the hero, Christy. Pegeen is writing a letter that shows her marriage to Shawn is approaching.

Say: "As in the classical manner" or "Typical of the classical manner".

insignificant, coward people

• insignificant, cowardly people

Shawn refuses to stay with her because he is afraid of Father Reilly .

Put a comma after "her".

he reveals that he had killed his father with a loy (a spade).

Delete "had".

Christy’ story of his past life is crucial to the play.

Place an es after the apostrophe.

saying that he was insignificant person in his village

Put "an before "insignificant".

We as audience feel sorry for him because of his father’s ill-treatment for him and at the same time, we are afraid to be in his own shoes.

Say: "the audience".

Widow Queen arrives at the shebeen although it is too late at night.

What is it too late for?

The fight starts between the two women.

Change "The" to "A". (You might be able to use "the" if the fight had been previously mentioned.)

At the end of Act I, Christy expresses his satisfaction of the fact that the two women fight over him.

Say: "his satisfaction about the two fighting over him".

After the girls and Widow Queen came to see him, he tells them his tale trying to make it sound as grand as he could.

Say: "he tells them his tale, making it sound as grand as he can". ("Making it sound as grand as he can" is an adverbial phrase.)

Susan says that his story is grand and Honor admires his way of telling the story.

Put a comma after "and".

This coming back of Old Mahon is essential to the play because it gives a comic relief.

Say: "because it provides comic relief".

If the patricide were actually committed, this would have been a gloomy effect on us.

Say: "If the patricide had actually been committed it would have had a gloomy effect on us."

Christy receives prizes for his victories in the sports

Delete "the".

There is a highly rhetorical love-scene between them. Although it is full of the use of figurative speeches on both sides, Christy’s and Pegeen’s, we cannot admit that the hero only use this rhetorical kind of language because Christy uses a simply language when we first met him in the first Act.

You might want to explain that "rhetorical" refers to the dialogue, and not leave that to the reader to figure out.

Christy now reaches the peak of his achievement in Mayo by getting the promise from Pegeen that she would marry him within fortnight.

Say: "that she would marry him within a fortnight."

Michael objects their proposed marriage, but he changes his mind upon seeing that Shawn is a coward and incapable of defending himself.

Say: "objects to".

This is also another climax in the play.

Delete "also".

Old Mahon comes back and begins to beat Christy.

I would prefer more detail there. Does he hit him with his fists? (When you say "begins to" does it really mean that the action was completed or even started?)

The people of the village have also turned against him for the same reason.

Instead of present tense, as before, here and later you switch to past perfect tense.

The village people tied him up with ropes in order to hand him over to the police.

Changing "tied" to "tie" puts that sentence in the present tense.

Nevertheless, not having been killed by the second blow, Christ’s father comes back again.

You didn't previously mention how many blows the man was dealt.

He departs and leaves Pegeen with a broken heart.

Why does he have a broken heart? That is not clear to me.

All in all, not bad. It is a big improvement over the previous version.
