How custom footer widget position / socket / text block ?

1/
On my footer, i have just 1 column. This one is on the left. How put this widget on the right and on center ?
2/
On my socket i would like my copyright on the left, and a contact link on the right. Like on your page: http://kriesi.at/contact
How to do it ?
3/ When I add a text block on a page and type a text, for the text size i have the choice between: paragraph / heading 1/ heading 2/ heading 3…
But this option set the size for all the text block. I would like to be free like on a Word document. I m looking for a solution for change the size of each sentence, each letter. Is it possible to add Font size ( 8, 9, 10, 11,12, 14,16….) ?

Thank you for your work
