Subshells are S, P , D AND F.
You only need to know S AND P if you are ocr.
Orbitals are a cloud of electron density where it is possible to find electrons ( 2 to be precise)
In the S subshell there are 2 electrons... So consists of one orbital.
P Subshell has 6 electrons....So consists of 3 orbitals (3 x 2) X Y AND Z all shaped like dumbbells on the axis mention (X y and Z)
The other two, although you don't need to know.... I.e D subshell contains 10 electrons so 5 orbitals.
