Hi,
1/ You can put the ads on the sidebar by go to Appearance > Widgets > drag & drop widget "HTML" to "Main Sidebar" and put the ads code inside this widget.
2/ If you want to do that, please use Elementor to config your homepage. You can check more on this video tutorial to know how to config homepage by use Elementor.
And when you use Elementor to config the homepage, you can use element "Penci Featured Boxes" to get your featured boxes appears.
