Add comments to regular web pages

I appologize if this is a stupid question. I am very new at all this and find myself incredibly overwhelmed. I’ve got WP installed and have been able to make posts with the direct URL of where I have WP installed but I want to show and allow comments to be made on several of my regular website pages. I have no idea if I can do this with WP and if I can I certainly have no idea how. Any help or insight would be greatly appreciated. Thanks in advance.
