Answer 1

Can we change the name of faces-config.xml file

Yes, but then it ceases to be a faces-config.xml file. It's hard to see why you're even asking.

or it should be the same name?

If you want it to work, yes.

In jsf 1.2 , default suffix is .jsp and jsf 2.0 default suffix is .xhtml? Can we have a default suffix as .jsf

Yes.

What is the use of the below line?

<listener> <listener-class>com.sun.faces.config.ConfigureListener</listener-class> </listener> here

See this answer, which you could have found for yourself.

How to get a managed bean name, scope and request url programatically?

The name of a managed bean is fixed when you compile it, so I don't know why you're even asking. I don't know what 'get a scope' means. You can get the request URL from the ExternalContext.

I have 1000 records in my database but i just want to show the records from 100 to 200 (in a jsf datatable? How can i do that?

With a LIMIT clause in your SQL.

How a request works in jsf?

Far too broad to answer here.

What is re-render and rendered attributes?

reRender is part of RichFaces. rendered is part of JSF.

what is the use of those?

These things are documented. There's no need to ask about things like that here.

difference between f:param and f:attribute?

Ditto.

where and when we use those?

Ditto.

Do we use none scope?

If you need it.

in what scenario it will be used?

When you don't need any other scope.

This questions are pretty frivolous. You could have more usefully spent the time doing some research of your own. Don't let me stop you.
