Selenium Wait for anyone of Element to visible

You can use or expected conditions for that

WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.or(
    ExpectedConditions.visibilityOfElementLocated(By.id("id1")),
    ExpectedConditions.visibilityOfElementLocated(By.id("id2"))
));

Or use cssSelector or ,

wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("#id1, #id2"));
