Each orbital can contain a maximum of 2 electrons only different in their spin momentum: +1/2 and -1/2.
The 4s orbital is fully 'used' from Ca (no.20) onward: 1s2 2s2 2p6 3s2 3p6 4s2
The 4s2 suborbital quantum numbers are: (s for spin direction: CW or CCW)
n=4, m=0, l=0, s= +1/2, or n=4, m=0, l=0, s= -1/2.
If it is in row 4 (4th period) it has 4 energy levels occupies. In the 2nd column (group 2A) it has 2 valence electrons. You ask how many orbitals it has. It has s and p orbitals. Is that what you mean? The configuration is 1s2 2s2 2p6 3s2 3p6 4s2 so there are 3 s orbitals and 6 p orbitals for a total of 9 orbitals.
The "formula" is n2 - so for principal quantum number 4 there are 16 orbitals, correspnding to one X s orital, three X p orbitals, five X d orbitals, seven X f orbitals.
The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.

Sp hybridized orbitals are formed when one s orbital and one p orbital combine to create two sp hybrid orbitals. These orbitals have a linear shape with a bond angle of 180 degrees. Sp hybridization commonly occurs in molecules with a triple bond, such as in acetylene (C2H2).
There are 4 orbitals in H2O , one s and 3 p

Hybridization comes from very complicated Quantum Mechanics and says that as many molecular orbitals that are being combound, the exact same number of hybrid orbitals are formed. Essentially, spherical s-orbitals and somewhat ellipcitcal p-orbitals are fused to make new orbitals that are identical. Example: 4 equivalent (tetragonal) sp3-orbitals in CH4 molecules.
The different orbitals are s orbitals, p orbitals, d orbitals, and f orbitals.
