Webform submission value token not working
Tapash, I've just tested this myself and I've had success with including the fieldset within the token so that it looks something like the following:

[submission:values:civicrm_1_contact_1_fieldset_fieldset:civicrm_1_contact_1_contact_first_name]

You'll want to update the above if you've customised any of the keys or are using a different contact!
