If you are trying to maintain a "global list", why are you throwing away everything in it every time you call that method, not once, but twice?

At the beginning, you discard any existing list:

C#

list = new List<string>();
string s1 = Fname;
...

Then when you have built a string to put in it, you discard it all over again:

C#

...
c += str1;
list = new List<string>();
list.Add(c);
...

TBH, it looks like you are guessing, copying code from random places without trying to understand it, and hoping it will magically all work in the end (The indentation is a big clue here, as is the code which generates the string - there is a lot of redundancy there).
That won't work: sit down, think about what you are trying to do, and design a solution instead of hoping and praying it will work. If you want a "global list", then you want to create it in one location, once only, and add and remove items as needed from there.

In class:

public class Test1Controller : Controller
   {
       static List<string> list;

       // GET: /Test1/
       #region Test1
       static Test1Controller() {
           list = new List<string>();
       }

Function

public ActionResult Generateid(string Fname)
       {
           try
           {
               string s1 = Fname;
               string s2 = "mpm";
               string x = s1.Substring(0, 1);
               string y = s2.Substring(0, 1);
               string z = s1.Substring(1, 1);
               string c = x + y + z;
               string s = "00";
               int number = Convert.ToInt32(s);
               number += 1;
               string str1 = number.ToString("D2");
               c += str1;
               list.Add(c);
               Session["sring"] = list;


               return Json(c, JsonRequestBehavior.AllowGet);
           }
