How can I adjust the footer on the Craft Theme?

Hello there, I’m trying to finish setting up my page’s footer and I want to:

  1. Align center the footer menu, I did find a solution but it also centered the text in brand information and I just want to center de menu and its title.

  2. Add a little space between brand information and social media icons, which belong to brand information, but I think it would looks better if I add spacing between the text and the icons.

  1. Reduce a little bit the space above the payment icons:

My store is: vivoinstantes.com and the password is: 1234

Sorry about my english, I’m not native speaker and thank you in advance for your suggestions.
