Dude! You just discovered a new language family! We could call it the "Indo-Aryan Languages" ;)
Not unless you change the word order.
3 parts to the sentence: Subject, object, verb
yah-log / javān / hain
these-people / young / are... Now convert to subject-verb-object syntax of English and you get: these-people / are / young
With that in mind, can you figure out how to order the words to say "These are young people"?
