The first clause is in the past perfect, so this is a 3rd conditional problem.

Rule is;
If + Past perfect / Past perfect continuous +,
+ Sub + would/could/should/must/might + have + verb in past participle.

No @Gowtham.

You can not use may instead of would.

Yes, it is a conditional sentence so use would instead of will.

Because it was his choice after knowing the condition wants to help him or not.

Yes, you are right @Shruthika.

Why we used have there, just "I would help him" is correct or not?

The sentence is formed as past tense.

"Will" is future tense, "Would" is the past form of "Will". That's why the sentence is wrong.

This is an example of 3rd conditional sentences:

IF + Past Perfect, would + Present Perfect.
It is used to talk about the hypothetical past situation.
