Hi Punith,
Answer to your questions below:
1) Beginning with SAP Mobile Platform SDK SP04, the capabilities of the SAP Fiori Client are provided through the Kapsel SDK as plugins for the Apache Cordova framework. This approach allows you to build your own version of the SAP Fiori Client and more easily customize it as needed for your environment.

2) To create an instance of the SAP Fiori Client, you need to manually create a new Cordova project, add Cordova and Kapsel plugins to the project and copy over web content into the new project. To simplify the process, the SDK release includes a node.js script (node create_fiori_client.js <configPath>) that you can use to create the SAP Fiori Client application project using the Kapsel plugins. Before executing that command, you should have shelljs already installed (npm install shelljs).

3) It doesn't require development of sapui5 app using cordova, you can just incorporate cordova library in FIORI app and launch the application in FIORI launchpad.
