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.

Electrons are generally gathered around an atom beginning with the lowest possible quantum numbers.
Barium (Ba) has the atomic number 56, and its electron configuration is [Xe] 6s². The quantum numbers for its outermost electrons are: for the two 6s electrons, the principal quantum number (n) is 6, the azimuthal quantum number (l) is 0 (s orbital), the magnetic quantum number (m_l) is also 0, and the spin quantum number (m_s) can be +1/2 or -1/2 for each electron. Thus, the quantum numbers for the two 6s electrons in barium are (6, 0, 0, +1/2) and (6, 0, 0, -1/2).
