Would you want to elaborate a bit more about your questions e.g.
- What do you mean by "9 areas"? Are the 9 areas within the same article? Or "9 areas" refers to 9 different articles?
- Is your custom module content the same for all the 9 articles?
- Not too sure why would you want to create a module and insert into an article. For such a case, most people would use a plugin. e.g. You might want to take a look at one of the other plugins I've written - the "Include Content Item" plugin
that allows you to easily insert the content of one article into another. With this, you can easily insert one article into as many other articles as you want. Coupled this with DirectPHP, you can insert PHP commands into the article to be inserted, and dynamically change the content for each article. (Just make sure that in the Plugin Manager, the order of the include_content_item plugin comes BEFORE that of the DirectPHP plugin.)
In any case, please give me more info so that I know how to help.
