They can only have 1 S ORBITAL per energy level (1s, 2s, 3s...). Each S orbital consists of 2 electrons of opposite spin.

There are five d orbitals in one energy level. These orbitals are designated as dxy, dyz, dxz, dz2, and dx2-y2. Each d orbital can hold a maximum of 2 electrons.
In the third principal level (n=3), there are a total of 3 sublevels: s, p, and d. This means there are 3 orbitals in the third principal level of the atom: one s orbital, three p orbitals, and five d orbitals, making a total of 9 orbitals.
d orbitals begin to fill after the s orbitals of the same principal energy level are filled, specifically starting from the 3d orbitals after the 4s orbital. This occurs due to the energy levels of the orbitals; while the 4s orbital is filled before the 3d, the 3d orbitals have a higher energy level compared to 4s once the 3s and 3p orbitals are filled. As electrons are added to an atom, they occupy the lowest available energy orbitals first, which is why d orbitals fill after the s and p orbitals of the preceding energy level.
The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
There is one s orbital and three p orbitals and five d orbitals in the third energy level.

There are 5 d orbitals in a given sublevel.
In the third principal level (n=3), there are a total of 3 sublevels: s, p, and d. This means there are 3 orbitals in the third principal level of the atom: one s orbital, three p orbitals, and five d orbitals, making a total of 9 orbitals.
3rd to onward all energy levels have 5 d-orbitals their name assign are dxy,dxz,dyz,d(x2 - y2) and dz2
The lowest energy level that contains d orbitals is the third energy level. Within the third energy level, starting with the 3d sublevel, the d orbitals become available.
There are five different d orbitals within the 3d sublevel: 3dz², 3dxz, 3dyz, 3dx²-y², and 3dxy.
In the principal energy level n = 3, there are s, p, and d orbitals. The s sublevel has 1 orbital, the p sublevel has 3 orbitals, and the d sublevel has 5 orbitals. These orbitals can hold up to a total of 18 electrons.
