1st conclusion should be Some mansions are huts. But mansion being middle term is in both the conclusion so none of the conclusion can follow.
If both the premises are A type the conclusion should be A type and should not contain middle term. If you don't agree then argue!

If we follow the rules then since both premises are affirmative the conclusion must be affirmative.
But according to contra positive the conclusion 1 follows.
I am confused since the rules and contra positive does not get me the same answer.
Please can anyone explain me regarding this.

This is how I see it.
Since both the premises are uni and affirmative, so the answer has to be uni and affir the middle term does not come in to the conclusion, so we get "All huts are temples" as the answer but they use contra-positioning and change the position of the subject and the predicate to get I.
