I am making web app using JSF 2.0 and Rich Faces 4.0 I want to know what should be minimum- entry in Web.xml and faces config.xml so that application will run successfully . Is order of servlet declaration matters , I am saying because when i am running my app with custom security filter, rich faces component is not rendering sometime . Can you please give me example Web.xml file.

I had the same issue in my project so I solved it by adding the path in the validation where the richfaces resources and jsf are being loaded.

Something like this:

String uri = hr.getRequestURI();            
if (uri.endsWith(".view")
                && !uri.contains(ResourceHandler.RESOURCE_IDENTIFIER)
                && !uri.contains(ResourceHandlerImpl.RICHFACES_RESOURCE_IDENTIFIER)) {
            //You put your code here
}

Just the usual FacesServlet mapping in web.xml is enough for JSF 2.0. The faces-config.xml can be left empty. RichFaces 4.0 doesn't require additional configuration in either file.

Update as per your update: you need to map your security filter on a different URL pattern. RichFaces will dynamically include CSS/JS files on the same mapping of the FacesServlet. However, your security filter is apparently blocking those requests (didn't you pay attention to those lot of system out prints in the log?). I'd suggest to put secured files in a folder and map the filter on there instead, e.g. /secured/*, /private/*, /app/*, etc.

Unrelated to the problem, you've got there a lot of FacesServlet mappings. Please keep it clean and stick to one. I'd personally recommend *.xhtml. This way the endusers won't be able to view the raw JSF source anymore by just editing the URL in browser address bar.
