Can I populate the user data like name and Email to my form? 

According to the Joomla! API, you can query the user's data with this PHP code:

//Name:
<?php $user = JFactory::getUser(); return "$user->name"; ?>
//Username:
<?php $user = JFactory::getUser(); return $user->username; ?>
//User id:
<?php $user = JFactory::getUser(); return "$user->id"; ?>
//Email:
<?php $user = JFactory::getUser(); return "$user->email"; ?>

Of course you can use this code in many places, for example copying this code into the 'Default Value' of a Textfield Element (Quickmode and Classicmode), the result is showed in the next form. 

Please note that you will only see the effect if you are logged in to our site!
