Method 1

Try to use get_term_by(), where first argument is a field, in your case – name. Second is your value. I used esc_attr() to make it secure. Third one is taxonomy, as example I put here category.

if ($_SERVER["REQUEST_METHOD"] == "GET" && $_GET['fname2'] && $_GET['fname']) {

    $nameb = get_term_by('name', esc_attr($_GET['fname2']), 'category');
    $namea = get_term_by('name', esc_attr($_GET['fname']), 'category');

}

//check if there is an objects 
if( $nameb instanceof WP_Term && $nameb instanceof WP_Term ){
     echo $nameb->term_id;
     echo $namea->name;
}
