I have to make a website in similar to.
hidden link
and
hidden link
Can you recommend a theme? Which plugins do I need. I am newbie with WP
I would reccomend the Toolset Starter theme and layouts for sure, this will allow you to create the Templates (the look of the site)

Then - I do not fully understand what the site does, but if you need to sell somethings, you need WooCommerce to create the Products and sell them.
If you need some sort of User Submission of Posts or even User registration, CRED is also needed.

The Content there seem to rely heavily on Custom Fields nad Types, so the Types plugin will help you to set up the Contents, and you can then display them in Layouts, using Views ShortCodes, which means, you also need to istall Views.

I suggest to first play a little with one of the Reference Sites here:
http://discover-wp.com/site-templates/
That is a free server where you can download or online replicate some ready-to-go Sites, all created with Toolset.
For single issues you find, I suggest you open a single Ticket each issue that will then help us to help you more focused.
