[amarkirt saroay]

If we have request.setAttribute("emp",e);

and In <jsp:useBean id="emp" scope="request" class="com.example.Employee" >
which of the following are correct to have ?
<jsp:setProperty name="emp" property="name" value="kt"/>
or <jsp:setProperty name="e" property="name" value="kt"/>

Which one is correct value for name attribute of setProperty and same way for getProperty also?

<jsp:getProperty name="emp" property="name"/>

or <jsp:getProperty name="e" property="name"/>

The name of the getProperty/setProperty must match the id of the bean. In your case, the id is "emp".
You can check this kind of thing in the JSP specification.
