Firstly, the file you've uploaded is from the poll plugin. Nothing to do with this one.
Then, in order to rename the badges, once you've selected Persian in the combo in the admin/general section you have to navigate to the Badge plugin options. In there you need to click on each badge an input a the name you want. Once you've done that you have to click Save.
For the space issue in the badges section go again to the plugin options and add this code at the end of the CSS text area:
.qa-template-plugin-badges [class^="qa-part-custom"] {
padding: 0 0 0 10px;
}
If you're using an RTL theme then try changing the padding to:
padding: 0 10px 0 0
Add the following code exactly in this line:
qa_set_template('plugin-badges');
