I can see one issue in your code and likely it is the root-cause of your problem.

  1. You have a static field driver
  2. You're trying to initialize (probably that static) driver in your first test. However you're creating an object WebDriver driver=new ChromeDriver();that is only locally-visible in your first test. Thus your static driver field remains uninitialized
  3. You refer to that static driver field in your other tests.

So here are few points I'd like to adivce

  1. It is worth reading a book or pass a course on Java before starting to implement auto-tests. This time you get the exception because Java cares about you but the next time you will get no errors but just a false-positive/false negative result
  2. Do not make your tests dependent on each other. Rather set up your driver in preconditions.

In addition to what Alexey R. mentioned, do you also need a JavascriptExecutor? you can easily click on links, e.g.: 

driver.findElement(By.id("clicked62")).click();

But mainly, since you are already using testNg, it would be better to initialize the browser (driver = new ChromeDriver();) in a @Before method (you can call this as:

public void initBrowser(){}

If you wish that way, the same driver will be initialized before each @Test.

And a sidenote: try to avoid using '*' in your xpath as the search scope in DOM is to wide. Its always preferrable to use a particular DOM element like //input[] or //div[].
