Can we use Yoast plugins on WordPress.com?
As of Yoast SEO 20.0, the settings interface inside our plugins has received a major overhaul. Please update to the latest version of Yoast SEO if your plugin does not look like the screenshots you encounter in our Help center.
The basic WordPress.com plan does not allow you to install plugins.
Upgrading to the WordPress.com Business or eCommerce plan allows you to install plugins from the official WordPress repository, like Yoast SEO, or upload custom plugins, like Yoast SEO Premium.

Please know that certain code snippets, such as the ones needed to implement Yoast SEO Breadcrumbs, may not work.
