Your code should be.

if (SName != null)    
    for (int i = 0; i < SName.Length; i++)
        Response.Write(SName[i]);

if (Email != null)
    for (int i = 0; i < Email.Length; i++)
        Response.Write(Email[i]);

The problem is that length of SName and Email are different.

It is not necessary you get same length for both SName and Email string arrays.

Index is out of bound because length are not same.

Better way is to do it separately:

string[] SName = Request.Form.GetValues("title");
string[] Email = Request.Form.GetValues("fname");

for (int i = 0; i < SName.Length; i++)        
   Response.Write(SName[i]);       

for (int i = 0; i < Email.Length; i++)
   Response.Write(Email[i]);

If you want to print one name and email then use this:

 string[] SName = Request.Form.GetValues("title");
 string[] Email = Request.Form.GetValues("fname");
 int iLength = -1; 

 if(SName.Length > Email.Length) 
     iLength = SName.Length;
 else
    iLength = Email.Length;

 for (int i = 0; i < iLength; i++)
 {
     if(i < SName.Length)
        Response.Write(SName[i]);          
     if(i < Email.Length)
        Response.Write(Email[i]);
 }

NOTE:

If you are not dealing with array of HTML element with same name then you don't have to use Request.Form.GetValues("title"). See following example:

string SName = Request.Form["title"];
string Email = Request.Form["fname"];

Response.Write(SName + " " + Email);

You can use the below code, which gives the result in a single loop

if (SName != null && SName.Length > 0 && Email != null && Email.Length > 0)
{
     for (int i = 0,j=0; i < SName.Length && j<Email.Length; i++,j++)
     {
          Response.Write(SName[i]);
          Response.Write(Email[j]);
     }
}
