I found elegant solution for custom fonts, different from Google Fonts.
1. Install WordPress plugin, called “Use Any Font”.
2. Activate the plugin.
3. Go to settings page of the plugin and get API key from the developers. They offer free API for one custom font.
4. Add your API key.
5. Upload your custom font.
6. You are ready to use your custom font for headlines, paragraphs, block quotes or add your custom elements: example for only one page, post, etc.
I hope this will help you.
