This might be a very basic question, but here it is anyway.
C-h f if
if is a special form in `C source code'.
(if cond then else...)
C-h f while
while is a special form in `C source code'.
(while test body...)
What is the difference between test and condition here for elisp
execution? Is test is a superset of condition? Is test considered
multiple execution of same condition ?

No difference. It just so happens that they used different wording.
if you are just beginning to learn lisp, you might be interested in my
