In other religions, people do meritorious things such as Dana and can obtain divine lives after their deaths. Will they also adore humans who do meritorious things and obtain merits?

Yes, see the Patigama Sutta http://www.palicanon.org/index.php/sutta-pitaka/khuddaka-nikaya/100-udana/938-ud-8-6-pa-aligama-sutta-at-pa-aliga-village. 

“In whatever place a wise person makes his dwelling, — there providing food for the virtuous, the restrained, leaders of the holy life — he should dedicate that offering to the devas there. They, receiving the honor, will honor him; being respected, will show him respect. As a result, they will feel sympathy for him, like that of a mother for her child, her son. A person with whom the devas sympathize always meets with hopeful things.”
