I've been working in simple and extensive Website Coding (PHP, MYSQL, WordPress (Theme Development),Drupal, Moodle, Zencart, Magento, Joomla, Java , JavaScript, JQuery, JQuery Mobile, CSS2/3, XHTML, HTML 5, Responsive Design, Bootstrap & LOT MORE), Website Designing and Graphic designing (Adobe Photoshop, Illustrator, Fireworks, GIMP, Dreamweaver) for over 10 years.
I've gone through your attached document and found the competitors web sites are done using following CMS s and Tools.
Ingenero - - Bootstrap
Energy Matters - - Dreamweaver
True Value - - WordPress
Mark Group - - WordPress
