Answer

Mujhe-to me
Teri-your(s)
Zaroorat- needy
Hai- is
Literally mean I need you

Answer

When you are in need of someone's help. This sentence is used.
Here, 
mujhe- me/to me
teri- you/your
zaroot- need
hai-  exist
That's roughly translates to "I need you" in english.

Answer

mujhe = to me
teri = your/you
zaroorat = necessary (in Arabic ضرورة)
hai = exists

Sentence would sound as ~ to me your necessity exists
and means ~ I need you/ You're important for me/ You're necessary for me

Answer

Song is..  
Haan mujhko teri zaroorat hai.

Its mean

Yes, I need you.
