            } else {
                firstname.setError("First name cannot be empty");
                lastname.setError("last name cannot be empty");
                email.setError("email cannot be empty");
                address.setError("address cannot be empty");
                mobile.setError("mobile cannot be empty");

Try,

Boolean valid = true;
if ( TextUtils.isEmpty(one) ) {
    firstname.setError("First name cannot be empty");
    valid = false;
} 

if ( TextUtils.isEmpty(two) ) {
    lastname.setError("last name cannot be empty");
    valid = false;
}

if ( TextUtils.isEmpty(three) ) {
    email.setError("email cannot be empty");
    valid = false;
}

if ( TextUtils.isEmpty(four) ) {
    address.setError("address cannot be empty");
    valid = false;
}

if ( TextUtils.isEmpty(five) ) {
    mobile.setError("mobile cannot be empty");
    valid = false;
}

if ( valid ) {
   Intent i = new Intent(main.this, next.class);
   i.putExtra("first", one);
   i.putExtra("last", two);
   i.putExtra("email", three);
   i.putExtra("mobile", four);
   i.putExtra("address", five);
   startActivity(i);
}
