Before creating the driver initialization, you have find the element and hence null pointer exception is throwing . Please change the code as below by moving the driver initialization part above the webelement

        System.setProperty("webdriver.chrome.driver","E:\\Chrome\\chromedriver.exe");
        driver=new ChromeDriver();

        WebElement popup=driver.findElement(By.xpath("/html/body/div/div[2]/a[1]"));
        WebElement name=driver.findElement(By.xpath("//*[@id='name']"));
        WebElement submit=driver.findElement(By.xpath("//*[@id='submit']"));
        WebElementproceed=driver.findElement(By.xpath("/html/body/div/div[2]/a[2]"));
