Answer 1

this is you problem

for (int i = 0; i < 5; i++)

this is your fix:

 static void Main(string[] args)
            {
                char[] Array = new char[5];
                Console.WriteLine("Please Enter 5 Letters B/W a through j only: ");
                string letters = "abcdefghij";

                char[] read = Console.ReadLine().ToLower().ToCharArray();

                //loop through array
                for (int i = 0; i < read.Length; i++)
                {
                    if (letters.Contains(read[i]) && !Array.Contains(read[i]))
                    {
                        Array[i] = read[i];
                    }
                    else
                    {
                        Console.WriteLine("You have entered an incorrect value");
                    }

                }

                Console.WriteLine("You have Entered the following Inputs: ");
                for (int i = 0; i < Array.Length; i++)
                {
                    Console.WriteLine(Array[i]);
                }
                Console.ReadKey();
            }
