but did not know how to display the status of the leds on the web server

The server serves up a page. The client (browser) displays the page, with the status.

The page that the site you linked to serves up contains button objects. You need to do some research about the button object, to see what properties/attributes you can set, like the title. You need to use those properties, or add other objects, like labels, to convey to the browser the additional information that you want it to show, in a way that it knows how to use.

String html = “”
“TCU_IOT”
“<form action=”" method=“get”>"
“<input type=“radio” name=“LED” value=“RED_ON1”> LED_ON1”
"<input type=“radio” name=“LED” value=“RED_OFF1”> LED_OFF1
"
“<input type=“radio” name=“LED” value=“RED_ON2”> LED_ON2”
"<input type=“radio” name=“LED” value=“RED_OFF2”> LED_OFF2
"
“<input type=“radio” name=“LED” value=“RED_ON3”> LED_ON3”
"<input type=“radio” name=“LED” value=“RED_OFF3”> LED_OFF3
"
“<input type=“radio” name=“LED” value=“RED_ON4”> LED_ON4”
"<input type=“radio” name=“LED” value=“RED_OFF4”> LED_OFF4
"
“<input type=“submit” value=“Submit”>”
“”
“”;

Line 50 sends the String webpage, which you have now called html. So, change that line...
