@jrdphd:
1. You have two options to select from by default, 3 columns and 4 columns. If you want to change further, it can be done through custom CSS. Let me know further for that.
For font and size, go to Dashboard=> Appearance=> Customize=> Theme Options=> Custom CSS box and add the following CSS:
/* Content */
#featured-post .entry-content {
font-size: 20px;
font-family: Times New Roman;
}
/* Title */
#featured-post .entry-title {
font-size: 30px;
font-family: Times New Roman;
}
2. For this, you’ll need to customize the theme. I recommend you to hire a customizer.
