Question about Zerif Pro

Hi Everybody.
First, congratulation for this lovely theme. That’s the one i’ll take for my website.
Before going to ZerifPro i have 4 questions if you don’t mind to answer.

1- For all sections, is it possible to change the size?

2- For all sections, is it possible to move up and reduce the size of the tittles?

3-On the big tittle section, is it possible to move up or down the big tittle and the 2 bottons?

4- On the focus section is it possible to reduce the size of the circles?

Thanks for your answers.
