You can use disabled attribute on any time along with JSF EL to pass the Boolean value to disabled attribute.
For example in your case If you want to disable any h:inputText if first name is pre-populated then:

<h:inputText value="#{countryBean.usersDetailsDTO.email}" id="empEmail"     
required="true" requiredMessage="Enter Email Address"      
disabled="#{not(empty countryBean.usersDetailsDTO.firstName)}">

The above code will disable the Email input text disabled if firstname is pre-populated.

You can handle this on 2 ways:

1) You set the disable-tag of the inputText to a BackingBean-method like this:

<h:inputText ... disabled="#{countryBean.found}" ... />

2) Adding a valueChangeListener on the first inputText, so if it has a text, the others should be disabled.
