I would like to change my Username, Profile Picture with my Team Logo and Cover Photo.

Actually all of my account will stay same. I only want to change my username, logo and cover_photo.
See screenshot: http://prntscr.com/kqlb6a

And want to add Company at Edit Profile Section, See Screenshot: http://prntscr.com/kqlcna

Otherwise, All other will stay same as current.
Is there any Policy Violence?

Strange, No reply yet.

You are making the changes in the wrong place.

Username is done: https://account.envato.com/

Logo and cover photo in https://themeforest.net/user/codersaiful/profile/edit (assuming you are logged in)

The ‘company name’ in your screenshot is only for paperwork purposes
