I have just implemented the Fivestar option in one of the evaluation form created by webform, I used the Fivestar module and Webform-fivestar module. But now I want to change the stars with different layout or design. In some of the article i read that we can change in manage display tab of the contentype but that option is not applicable for webform components. So that changing option is not available in the webform configurations. So please help me how to achieve this.
The webform-fivestar module currently doesn't have the option to select which star widget to use, however there is a patch you can apply at https://www.drupal.org/project/webform_fivestar/issues/2071161
There is information regarding how to apply patches at https://www.drupal.org/patch/apply
You can then select the widget per component, when editing the component, in the display settings (see screenshot).
