There is one subshell in the f orbital, which can hold a maximum of 14 electrons. This subshell has seven orbitals: 5f with each of the orbitals capable of holding 2 electrons.
6 electrons in 3 orbitals of p-sublevel: px, py and pz
Maximum capacity of electrons in f-orbitals is 14, so 4f orbitals may have 1 to 14 electrons.
The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.
The number of electrons in a subshell of a copper atom depends on which subshell you are referring to. Copper has 29 electrons, so its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d9. The 3d subshell in copper contains 9 electrons.
There is one subshell in the f orbital, which can hold a maximum of 14 electrons. This subshell has seven orbitals: 5f with each of the orbitals capable of holding 2 electrons.
In theory all elements have all the orbitals. Zinc has electrons in four of them.
Iodine has 7 electron-containing orbitals, corresponding to its 7 valence electrons in the p subshell. These orbitals can hold a maximum of 2 electrons each.
16 orbitals
All p sublevels contain three orbitals, including the 4p sublevel.

Maximum capacity of electrons in f-orbitals is 14, so 4f orbitals may have 1 to 14 electrons.
If the question is an attempt to ask "How many orbitals are there with principal quantum number n = 2", then 4 orbitals which can hold a total of 8 electrons.

9. The number of orbitals in a given shell fit the equation 2(L)+1, where L=the angular quantum number. L=0 corresponds with the s orbital, L=1 with p orbital, L=2 with d orbital, L=3 with f orbital, L=4 with g orbital, and L=5 with h orbital.
The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.
