The shell is a command interpreter which stands between you and the kernel.
Sed is an editor, the rest are programming languages with various focusses,

The shell includes a high-level and immensely practical programming language,
and you would be very wise to learn an sh-compatible shell like bash or zsh,
before tackling any of the other languages.
And then, once you have a handle on 'sh', skip the rest and go for broke:
learn C, (which most of the others are written in :-)
Learn the stream editor sed because it is very, very useful.
