Render values directly in a twig paragraph template
I'm new to Drupal also and was trying to do the exact same thing. I simply put the machine name of the input I was trying to show in to the twig template i.e - {{ field_image_caption }} - flsuhed the cache and it magically appeared. Hope that helps.

&lt;div class="slice h-clearfix"&gt;
    &lt;div class="l-col-12 l-content t-content article-content"&gt;
        &lt;div class="l-col-10 l-push-1 l-padding"&gt;
            &lt;div class="article-image"&gt;
                {{ field_image }}
                &lt;div class="article-img-social"&gt;
                    &lt;div class="article-caption"&gt;
                    PHOTO CREDIT: {{ field_image_caption }}
                    &lt;/div&gt;
                &lt;div class="article-img-share share-article-image"&gt;&lt;/div&gt;
            &lt;/div&gt;
        &lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
