The language switcher is used for the WPML plugin. After installing the WPML plugin, you can add/edit languages in its setting page. If you don't use the WPML plugin, you can remove it by going to Theme Options > Header tab and disable the Header Language option.
I see you changed the site's logo. If you want to change footer content or the logo in footer, you go to Footer Blocks and edit Footer Block which you use. For more information about adding and managing footer, please read our documentation http://demo.theme-sky.com/documentation/sanzo/#footer

Hi arkadynet,
The language switcher is used for the WPML plugin. After installing the WPML plugin, you can add/edit languages in its setting page. If you don't use the WPML plugin, you can remove it by going to Theme Options > Header tab and disable the Header Language option.

The subscription form is also in Footer Block. It is the TS Feedburner Subscription element. You also go to Footer Block and change it. To know how to configure Feedburner, please read this article http://www.wpbeginner.com/beginners-guide/step-by-step-guide-to-setup-feedburner-for-wordpress/. If you want to replace it by a Mailchimp form, you can install the Mailchimp for WordPress plugin and use html in our documentation http://demo.theme-sky.com/documentation/sanzo/#shortcodes
