theme customizer: change position widgets footer

Hello, I need help with alignment of the widgets that I have on my website footer. I have three areas of widgets, the first two are misaligned and I’d like to move slightly toward the center of the screen. I searched this forum, but the only solution I’ve found what makes me is to move these areas further to the right but also the words are aligned to the center, I want the words to remain flush left but the area where they are to be placed a little more to the center. The third area that appears only a phone number is the only one that is well aligned and focused.
Can anybody help me? Thank you.
Here is the link to my site so that it is displayed.

I also like to know how can I increase the text size of the words that go into the footer. I increased the font size overall page but has not specifically raised me of the words of the footer, which is still very small.
Thanks, I hope your answers.
