Customizing Camera Man Template

[my add]

I got the Camera Man template which has a nice header of a collage of a bunch of pictures that change in a slide show sort of way and I was wondering if there is any way that I can customize all of the pictures in the header as well as the part in the center of it that says:
I am Nicolai, I am a…
Model…
Photographer…
and so on…
(because for sure not a model ;) )
I am not very fancy on code and I’m not really sure where to find the CSS code for the Camera Man template, so any help would be nice!
Thanks so much for the help in advance!

Find this in the html template:
Where it says Hi, I am Nicolai, add your own description

<!-- Change the slogan Here-->
<div class='above-grid'>
<p>Hi,, I am Nicolai, I am a <span id='demo'></span></p>
<!--Top Social Icons-->
<div class='container4'><div class='row1'>
<ul class='social-items'>
<li><a href='#'><i class='fa fa-facebook'></i><div></div></a></li><li><a href='#'><i class='fa fa-twitter'></i><div></div></a></li><li><a href='#'><i class='fa fa-youtube'></i><div></div></a></li><li><a href='#'><i class='fa fa-google-plus'></i><div></div></a></li><li><a href='#'><i class='fa fa-linkedin'></i><div></div></a></li><li><a href='#'><i class='fa fa-pinterest'></i><div></div></a></li>
</ul>
