What is wrong with each of the following while loops for Problem 3?

Note: first answer was given 6 times 

while ( (x != 1) || (x != 2) || (x != 3) || (x != 4) || (x != 5) );

while ( (a == 1) || (a == 2) || (a == 3) || (a == 4) || (a == 5) );

while ( (input !== 1) || (input !== 2) || (input !== 3) ||
        (intput !== 4) || (input !== 5) );

while ( (input < 1) && (input > 5) );

while ( (1 < num) || (num < 10) );

while ( (temp > 5) && (temp < 1) );

while ( (number > 0) && (number < 6) );

while (scan.nextInt() != 1) || (scan.nextInt() != 2) ||
      (scan.nextInt() != 3) || (scan.nextInt() != 4) ||
      (scan.nextInt() != 5));
