Adjust content in Charm Templet

Hello,
My Joomla skills are low.
I bought and installed Charm Templet.
Is it possible to change the photos and other information such as telephone numbers, e-mail addresses without programming skills, if so where?
The plan is to establish a communication or dating platform. More difficult than expected.
Are there any video tutorials. My page http://www.sorelax.ch
Thank you

Greeting
Wladimir
