I'd say you're confused, badly. Start with
Getting Started with ASP.NET MVC 5 | The ASP.NET Site[
^] .
If that doesn't clear anything up, I suggest picking up a book on MVC and working through it. Everything else you find on the web is going to follow the same stuff as the above link.
1) Not possible to answer this. It's essentially asking "how do I write code".
2) MVC uses template files to generate HTML for the browser using a view engine. That can be either Razor, Spark, NHaml or ASPX currently. You can also provide your own view engine implementation. Razor is HIGHLY recommended. DO NOT mix template page types. For example, do NOT use .CSHTL and .ASPX pages in the same project. Pick one view and engine and stick with it throughout the project.
3) This question is meaningless.
4) Yes. Yes you can pass Json formatted objects to MVC Controller methods.
5) Yes.
