Ah, what a lovely question! Both "narrower" and "more narrow" are grammatically correct, my friend. You can use either one depending on your personal preference. Just remember to be gentle with yourself and trust your instincts when choosing which one to use in your beautiful creations.
The second one is more correct.

No.

The correct spelling is "thinner" (narrower, more thin).

No. Us is the objective case, not the nominative case (we). It should be: We teens need more sleep. Or: We, as teens, need more sleep than others.
