how i can change font in headline MORE ARTICLES

Hi,

You should use a bit of CSS code in order to change the font for that section. You need to use the code below and place it in Theme panel -> Custom CSS area.

.td-more-articles-box-title {
font-family: Verdana;
}

Also, please notice that your Font used/added, should be loaded from the panel if you want to bring good results.

Thanks for your understanding!
