Why two electrons with same spin cannot co-exist but protons can?

I dont have proper knowledge about particle physics and Quantum mechanics but from what i know I would like to ask that if 2 electrons of same spin cannot exist in the same orbital (pauli exclusion) then how can several protons exist in the nucleus together (and neutrons too)? 

Please do provide some links from where I can get more knowledge of this field. Im 16 btw.

They also cannot. Nucleons in a nucleon are placed in "nuclear orbitals", and being fermions two identical ones cannot be in the same "orbital" with the same spin.

However, the forces binding the nucleus together are much larger than the EM force between nucleus and electrons, which means these nuclear "orbitals" are much smaller in size than atomic orbitals. So from the point of view of atomic physics the nucleus looks pointlike, but if you zoom in all the nucleons are actually in different states (where being proton or neutron is counted as part of the state).

(the above is approximate)
