sh - Bourne shell: the original unix shell, used for root account, hasn't changed much.
ksh - Korn shell: much more functionallity, better constructs for looping and testing, more built in variables and better process handing.
csh - C shell: created to mirror C language, apparently easy for C programmers to use
bash - Bourne Again Shell: created as the default shell in linux, then ported back to Unix, pretty similar to ksh
tclsh - Tool Control Language Shell: Very extendable language, very useful for prototyping and / or integrating with wish (Windowing Shell) a basic GUI creating shell

sh,ksh,bash shares one command language, (set variable=value ; export variable)
csh,tcsh shares another, (setenv variable value)
tclsh,perl etc are shell (or interpreters)  for underlying tcl,perl etc interpreted language
