portfolio page icons and equal eight columns

Hello
I need to display something link in the link below
but I have different problems

1) I added 4 layout element but I need them to be of the same size / height, now they are not. How can I do that? Maybe I should use something different?
2) I need to add social icons inside the last box with image + link to the relative social network. Is that possibile?
I tried to use font awesom shortcode <i class=”fab fa-instagram-square”></i> but it doesn’t work
3) I don’t want to have the sidebar in portfolio pages, how can I hide it in all portfolio pages by default? I’ve just find out how to hide it in a single page
4) I noticed that when I use bold the color of the font changes and it is the one of the linked words (anchor text) … but I don’t want that. Is it possibile to have bold words on different color?
5) I am using boxes with icons but I can see only few fontello icons … it’s not possibile to have the free set of font awesome??

Please let me know

Thank you very much
