Hello, Shiv The only wrong construction is sentence #1. "Went" is the past tense of "to go", and the past tense doesn't as a norm use an auxiliary verb in affirmative statements. " You used "has" correctly in your second sentence: together with the past participle of a verb, "has" and "have" form the present perfect.

All but 1 and 5 are correct.
1. An auxiliary verb ''have" attracts a past participle "gone" and not a past tense "went" in the given sentence.
5. The "bag" should be pluralized because of the usage of "some other". So "The book might have been kept in some other bags" Or "The book might have been kept in another bag".
