Featured image slider

Hi Catch Theme Team, I have a few questions. Seeking your expertise to bail me out. 1. How can I limit the number of posts on the slider. I want the latest 5 posts to display on the slider and not the older ones. 2. Is Simple Catch a responsive theme or not? 3. How can I reduce the size of Featured Image Slider. I want to reduce height of the slider. 4. Can you recommend a compatible Call Now button plugin for this theme? The ones I searched on WP are not compatible with Some Catch.
