How To Display Featured Posts From Multiple Blogs in Shopify?

Solution:

Could you try this? Just add some more block schema

    
<div class = "blog-container">

    {% if section.settings.blog != blank %}
    {% for blog in section.settings.blog %}
     
     <p>{{blog.title}}</p>

    {% endfor %}

{% endif %}

{% if section.settings.blogone != blank %}
 {% for blog in section.settings.blogone %}
     
     <p>{{blog.title}}</p>

{% endfor %}

{% endif %}


{% if section.settings.blogtwo != blank %}
 {% for blog in section.settings.blogtwo %}
     
     <p>{{blog.title}}</p>

  {% endfor %}
{% endif % }
     </div> 

 {% schema %}
{
  "name": "Blog posts",
  "class": "index-section",
  "settings": [
    {
      "type": "text",
      "id": "title",
      "label": "Heading",
      "default": "Blog posts"
    },
    {
      "id": "blog",
      "type": "blog",
      "label": "Blog"

 {

    },
 {

      "type": "blog",
      "label": "Blog Three"
    },
    {

      "label": "Show 'View all' button",

      }
    }

}
{% endschema %}
