Header – 4 logos

Good morning,
sorry I´m there again, but I have a big problem and and I don´t know how to fix it.
I need four logos in one row in header two. All the time I was using header two, one logo left and one logo right (Header Layout/Additional Text Box) and it worked fine. Now the customer has to build up four different logos in the head.

So i put 3 logos in the Additional Text Box

On the mobile phone, they are hidden and that is fine with me, but on the Ipad (Portrait) they are all over the main logo.

Can you please help me?
Do you have an idea, how i can integrate the 4 logos, so they are responsiv or not show up on mobile?

Greetings Melanie
