1. As you are using Catch Everest Free theme you have option just to just “Featured Post Slider”.
For this, you need to create the post and add featured image in your post.
Go to “Appearance => Theme Options => Featured Post Slider” in your WordPress Dashboard
To add Posts in the slider, click on Slider Options and simply insert the ID numbers for posts in the boxes, one post ID number in each box
