Hello,

1) Please provide a relevant screenshot of the specific area that you want to change the brand logos to check it myself and help you out accordingly. Because the screenshot you provided doesn’t have the brands.

2) You can change the button colors from Theme Settings >> Styles and Colors.

3) It seems that you have set the blog style to masonry that’s why it is displayed like that. You can change the blog style from Theme Settings >> Blog.
