Yes. The last quantum number is the magnetic spin which has values spin up (+1/2) or spin down (-1/2). Two electrons can have the same first three quantum numbers, but will not have the same four because one electron will be spin up and the other spin down.

Yes you can have the same 3 quantum numbers since each orbital can hold two electrons. Thus, two electrons in the same orbital would have the same first three quantum numbers but have a different spin state.

Yes you can have the first three be the same the fourth being the spin will be different if the first three quantum numbers are the same. Two electrons that have the same first three quantum numbers are in the same orbital, but then will have different spins (up or down)

Only two electrons can have the same first three quantum numbers. No two electrons have the same 4 quantum numbers and this is because the last number, indicating electron spin, is different. The two electrons with the same 3 quantum numbers will have a different 4th quantum number.

Yes, the first three quantum numbers of an electron can be the same but the spin must be different because all four quantum numbers of different electrons can not be the same.

Yes, if the spin quantum number is +1/2 for one electron and -1/2 for the other.

Yes because the 4th quantum number relates to spin and the spin can either be +1/2 or -1/2.

Yes, the first three quantum numbers can be the same, but the fourth must be different as each electron on that orbital would have a different spin.

It is possible to have the same 3 quantum numbers, but it is not possible to have 4 of the same. The four quantum numbers determine the magnetic spin (1/2 or -1/2.)

This is just a clarifying question, but with the last 2e- on the same orbital, one will spin up and the other will spin down right?

Yes, however the spin quantum number has to be +1/2 for one and -1/2 for the other electron.

Yes, you can have the same 3 quantum numbers, but the 4th number is the spin quantum number. Only two electrons can have the same first 3 quantum numbers, this is because the spin number only has two values (+1/2, -1/2.)
