It is always helpful to show a different number of questions on the homepage. There is nothing worse then those long lists of FAQ questions which really don't apply. By showing, for example the most common questions on your homepage or a selected few from each category will help promote user engagement. You can show as many articles as you want. 

This is very easy to change, and you can do it by inserting or changing the variable limit inside the for loop. If you're still confused, take a look at this real life example below.

We're currently inside Customize -> Index page and we can clearly see the variable, limit:3. Changing that to another number, for example, limit:10, would change how many articles will appear on your homepage, in our example it will show 10 articles.

{% for subcategory in category.ordered_subcategories limit:3 %}
 <li>
   <a href='{{subcategory.url}}'>
     <b>{{subcategory.name}}</b>
   </a>
 </li>
{% endfor %}
