"Orbital" is ambiguous, as it can mean different things depending on the context.

p orbital contains three orbitals p_x, p_y and p_z.

You should say p "subshell" contains three orbitals p_x, p_y and p_z.

And OP can use the formula :

Number of orbitals = n² , where n is principal quantum number.
