I can't figure out how to use -yl on organic nomenclature and how do I use it in nomenclature. Please explain everything about the use of -yl in nomenclature.

$\begingroup$ Think of the ending -yl as defining an adjective. The term (butan-2-yl) is an adjective modifying the noun tert-butylbenzene. No different than 3-methylhexane. [3-adjective-noun]. $\endgroup$ – user55119 May 15 '18 at 18:03

The "yl" refers to removing a hydrogen atom from a molecule making a univalent group.
Butane is
$\ce{CH3-CH2-CH2-CH3}$
To make butan-2-yl take a hydrogen atom off carbon 2:
$\ce{CH3-CH-CH2-CH3}$
Then butan-2-yl X would be
$\ce{CH3-CH(X)-CH2-CH3}$.
