How can I customize my website's footer blocks, text alignment, and header font size?

Can I get the code for these:

I need to align my footer blocks -policy column to the right , subscribe to my email column in the middle above the policy column, and social media icons below the line

I want the text on my pages to be center and bold.

I want to make the ‘shop’, ‘about us’, ‘contact us’ text on my header size bigger and change their font.
