Check out Doc_Skins ? Roundcube Webmail and Doc_SkinML ? Roundcube Webmail

In the document you provide, code for implementing is given. But how can I define those. It means if I define a label, how can I set the text of the label?

You would need to make a plugin Doc_Plugins ? Roundcube Webmail or modify the RoundCube localization files.
