4s 3p 3s 2p 1s
This is probably one of the easiest chemistry problems in the book, you should probably look it up.
2s, 3p, 4s, 3d
4s>3p>3s>2p>1s.
5s
There are 2 energy sublevels in the second principal.
There are two sublevels in the 2nd principal energy level. They are the 2s and 2p sublevels.
filled energy sublevels

There are five sublevels in the fifth energy level: 5s, 5p, 5d, 5f, and 5g.
There are 2 energy sublevels in the second principal.
There are two sublevels in the 2nd principal energy level. They are the 2s and 2p sublevels.
Increasing the wavelength results in decreasing the frequency and decreasing the energy.

Depends on what one means by "smaller". Since sublevels are "inside" or part of the principle energy level, then yes, they are smaller.
There are five sublevels in the fifth energy level: 5s, 5p, 5d, 5f, and 5g.
In krypton atoms, the 3s and 3p sublevels are filled, i.e. 3s23p6.
