you need Various Javascripts functions to validate each textboxes.
check following code.

//for Textbox1 - check for empty

JavaScript

function checkEmpty()
{
  if (document.getElementById("Textbox1").value=="")
     {
         alert("Please enter value in textbox1");
         document.getElementById("Textbox1").focus();
         return false;
     }
}

//for Textbox2 - EMail validation

JavaScript

function checkEmpty()
{

filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
  if (filter.test(document.getElementById("Textbox2").value))
     alert ("valid")
  else
     alert ("Invalid")
}

//for Textbox3/5 - check for Numeric and alphanumeric

JavaScript

function checkInt()
{    
    if (isNAN(document.getElementById("Textbox3").value))
	alert("Text is alpha numeric, Please enter only numbers");
}

//for textbox 4 - special char validation

JavaScript

function checkSpecialchar()
{
 var iChars = "!@#$%^&*()+=-[]\\\';,./{}|\":<>?";

  for (var i = 0; i < document.getElementById("Textbox4").value.length; i++) 
  {
  	if (iChars.indexOf(document.getElementById("Textbox4").value.charAt(i)) != -1) 
        {
  	  alert ("do not enter special char.");
  	  return false;
        }
  }
}

//for textbox 6 - Date validation

JavaScript

function checkSpecialchar()
{
  var date_chk = /(?:0[1-9]|[12][0-9]|3[01])\/(?:0[1-9]|1[0-2])\/(?:19|20\d{2})/;
  if (! reDate.test(document.getElementById("Textbox6").value);) 
  {
     alert ("Invalid date");
     return false;
   }
}

hope this helps.
