Am able to load and call the functions but I would like to reload the file after making some corrections.
Cant find either an unload or reload function?

Unloading is not really possible. It is for example possible to delete a package and thus remove its definitions. But other references to a symbol of that package might still exist.
The typical way to deal with that is to load a file again, as Vijay Mathew mentioned.
It might be helpful that the file loaded is written in such a way that reloading is possible.
A few remarks on reloading:
functions/macros will be replaced with the new definition.
functions/macros in existing code may not be replaced due to inlining/macro expansion.
CLOS classes will be updated, its instances will be lazily updated.
Structure definitions will be updated, existing structure instances will not be updated.
DEFVAR replaces a value if one doesn't exist. DEFPARAMETER always replaces a value.
Just use load again.

As @user713516 points out, if you deleted or renamed functions or variables from your file, reloading it will not delete those old definitions. This will be very confusing if you forget a reference to such an old definition: it will still be called and you'll wonder why the new definition isn't working. Lisp's REPL based reload workflow is the only one suffering from this problem.
