(1) Electrons occupy in the lowest energy orbitals. The increasing order of orbital energy is s, p, d and f. The lowest energy orbital is 1s. The order of energy of the orbital for the for the first three period is given below,
1s, 2s, 2p, 3s, and 3p.

(2) The orbital which is closer to the nucleus has lower energy, therefore the 2s is lower in energy than 3s. Accordingly 2s is lower in energy than 2p and 4s is lower in energy than 3d.

(3) In general, the orbitals can hold maximum of two electrons, the two electrons must have opposite spin.

The subshell ordering by Aufbau principle is given below, 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s, ...
