1/ Enable Elementor editor for the Static blocks https://xstore.helpscoutdocs.com/article/47-static-blocks
After that go to Static Blocks and edit the Footer static block using Elementor.
2/ Likely custom header is used on Home page, go to Theme options > Header builder > Multiple headers > edit header for the Front page. Here is a video about Multiple headers – https://youtu.be/BpeXfzNwkOc
