            int[] ticket = new int[5];
            string[] nome = new string[5];
            for(int i = 1; i < 6; i++)
            {
                Console.WriteLine("Bem vindo, digite seu nome: ");
                ticket[i] = i;
                nome[i] = Console.ReadLine();
                Console.WriteLine("Ticket número {0} do Sr. {1}", ticket[i], nome[i]);
                Console.WriteLine("Pressione Enter");

            }
            Console.ReadKey();
        }   
    }
}

The error that appears is:

An unhandled exception of type 'System.IndexOutOfRangeException' occurred in Testes.exe

Your array is declared as having 5 items:

int[] ticket = new int[5];

The problem with your code is to assume that the first item in the array is indexed 1.
Array indices in C # and most languages start at 0.

As for your for the code will access index item 5 which goes beyond the length of the array.

Change your for cycle to:

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

One way to avoid this type of error is to use, in condition, the Length property of array :

for(int i = 0; i < ticket.Length; i++)
