I have a requirement, I want to display file: link's file type info on the link.
For example, an Org file: link
#+begin_src org
[[file:~/Org/logo.png][logo]]
[[file:~/Org/document.pdf][document]]
[[file:~/Org/book.epub][book]]
#+end_src
I want to display link as:
#+begin_src org
logo (image: png)
document (document: pdf)
book (ebook: epub)
#+end_src
I'm inspired by this code snippet:
#+begin_src emacs-lisp
(org-link-set-parameters
"file+sys"
:complete 'org-file-complete-link
:face (lambda (path) (if (file-exists-p path) 'org-link 'org-warning)))
#+end_src
Is it possible to display those info between parentheses with an overlay or
propertied text?
If someone have any idea or how to implement this, please help me. Thanks in advanced.

I think you are looking for the :activate-func property of a link. What
you want is somewhat tricky though, how would you edit the link?
There is an example at
https://kitchingroup.cheme.cmu.edu/blog/2016/11/04/New-link-features-in-org-9/#org069cbfa
that might give you some ideas. You can use a 'display text property to
change the appearance, but you need some way to remove this if you want
to edit or see the original version.

I usually edit link with =[C-c C-l]= to edit link URL and description, not literally.

In that case:
#+BEGIN_SRC emacs-lisp
(defun file-description (start end path bracketp)
(put-text-property start end 'display (shell-command-to-string
(format "file %s" path))))
(org-link-set-parameters
"file"
:activate-func 'file-description)
#+END_SRC
With this, you have to have a way to insert links that isn't typing them in
by hand; as soon as emacs recognizes the link, it changes the display which
makes it hard to type.
The shell command puts a long string, so you might replace that with
something that has the output you wanted above.
