There can be two electrons with those quantum numbers in an atom. Each electron is completely described by four quantum numbers. The one that's missing in the list provided is ms, which can have only two possible values (+1/2 and -1/2).
The Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers. This includes the spin quantum number, which can have values of +1/2 (up) or -1/2 (down). So, in the 1s orbital, the two electrons must have different spin quantum numbers to adhere to this principle.
Pauli's exclusion principle
The four quantum numbers, n, l, m1, and ms, are all solutions to Schrödinger's equation. These numbers are used to assign each electron in an atom an "address." They "uniquely characterize an electron and its state in an atom" ("Quantum Number").
10 electrons.The angular momentum quantum number is l (small L). This quantum number is dependant on the principal quantum number, and has values, 0 1,2 ..(n-1), where each value of n refers to a subshell known to chemists as followsn= 0, s orbital; n=1, p orbital; n= 2, d orbital; n= 3, f orbital.So we are looking at the d orbitals.There are five d orbitals, with magnetic quantum numbers running from -l to +l, that is -2, -1, 0, +1, +2Each of these can hold 2 electrons (with spin quantum numbers -1/2, +1/2)So we have 10 electrons that can have pricipal quantum numbers of 4 and angular monmentum quantum number of 2.

Electrons are assigned quantum numbers to uniquely describe their energy levels, orbital shapes, and orientation in an atom. These quantum numbers help to characterize the behavior of electrons within an atom and are essential for understanding quantum mechanics and the electronic structure of atoms.

The energy levels and orbitals the electrons are in
Four quantum numbers are used to describe electrons in atoms.
In theory, the number of electrons with each quantum number is not limited. However, for any given "main quantum number" (n), the number of electrons having the other quantum numbers is limited - but it depends on the value of "n". For more information, the Wikipedia article on "quantum number" seems to give a good overview.
Just two, +1/2, -1/2. These correspond to electrons of opposite spin.

Pauli's exclusion principle
Electrons are generally gathered around an atom beginning with the lowest possible quantum numbers.
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
