Answer 2

To Change specific App icon:

1. I suppose, the icon which you want to place is ~/Downloads/[image.png]

2. Open terminal and run the commands:

   nano /usr/share/applications/[appname].desktop
   

Note : If you don't know exact app name, use ls -l

3. Now replace Icon=[path] with Icon=/home/[username]/Downloads/[image].png

Now save and exist.
