add multiple Social media hyperlink to home page

Hi,
i-amaze well provided the hyperlink and icon of some of the social media such as Instagram, Twitter, and so on.
1) I want to add multiple Instagram page hyperlink. how can I modify the code to add one more Instagram icon with a different address page? after the change applied, how can I deploy the code? just saving the code in WordPress means deployment?

2) how I can add more social media icons that not available in i-amaze?

thank you
