Yes. Why? well its electron geometry (trigonal planer) tells us that it is sp2.
sp2
Single elements on their own do not have a hybridization. Hybridization only occurs when there is a central atom with other elements (or lone pairs) coming off of it.
SP2
The carbon atoms are sp2 hybridised.
The central atom of ammonia is nitrogen and it has 3 bonding pairs and a lone pair around, hence it undergoes sp3 hybridization. The central atom of boron trifluoride is the boron atom, and around it has only three bonding pairs. So it hybridizes as sp2.

Carbon, the central atom, is sp2 hybridized.
Prsumably you mean AlH4- the tetrahydroaluminate anion. The hybridization of the central atom of AlH4 is sp3.
sp2
sp2 since the (graphical, with respect to resonance) Lewis structure for NO3- is: one oxygen double bond, the other two is single bond. an electron of N (which have 5 valence e-) is "donated" to O. And an electron gained by the anion is placed on the other O.

its sp2 hybridisation

sp2. Even though there is a double bond the hybridization will be sp2 (with the pi-bond considered non-hybridized)
