Remaining 02 can be inline with Title. However all the coming inline with title. The file baposter.cls is available here baposter.cls. The code is as follows:

• Hi and welcome. I have these error ! LaTeX Error: File "baposter.cls" not found. Where do you find this class? – AndréC Jul 25 at 19:52

Welcome to TeX.SE. You can set a logo on the left of the title by adding eyecatcher=true and then using \includegraphics... to add the logo. The logo on the right is also added using \includegraphics.... To get logos in the upper left and right of the page, you can apply them on the background using the \background macro.
