That's complicated, because you don't want to go anywhere near character arrays to do this: they are harder to work with for inserts than strings are!

Start with identifyign teh location of your "insert points" - in this case the numbers.
As simple regex will do that for you:

\d+\s

The Rexex Match includes the Index property[^] which tells you where in the string it found the number.
You can then use the index with the string.Substring method to break the string in two, and build a new one from the parts:

C#

string old = "Abcd";
int index = 2;
string new = old.Substring(0, index) + "xx" + old.Substring(index);

Will give you a new string containing "Abxxcd".

You will probably want to work from the last match backwards...

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            string strString = "1 I am good and 2 how are you";

            Char[] charReader =strString.ToCharArray();

            Console.WriteLine();

            string strInclude = "htmltag";

            Char[] charInclude =strInclude.ToCharArray();

            foreach (char ch in charReader)
            {
                if (char.IsNumber(ch) == true)
                {
                    Console.Write(ch+" "+ strInclude);
                }
                else
                   Console.Write(ch.ToString());
            }
            Console.ReadLine();
        }
    }
}
