add top-sidebar at right (or bottom) at theme logo

In theory yes, but if you add a link to your website I can probably be more precise. What theme are you using?

First of all make a child theme
Then try to add this code to your custom CSS

#nav-header.nav-container {
   background: transparent;
   top: -90px;
   box-shadow: 0 0px 0;
}

#page {
   margin-top: -100px;
}

(background color is temporary)

my idea is place one widget text area with news ticker in header bar… at right the site logo!

I’m afraid this is not possible without custom coding. And I’m not saying CSS, I’m saying php. You have to add the code that creates the sidebar in the header area, and then add the widget. If you try to move one text area on the current sidebar to the top with CSS you’ll move also all the other widget areas because they’re all tied together
