What part is not clear.

Doc are more than enough. I feel...

$route['product/(:num)'] = "catalog/product_lookup_by_id/$1"; In this example what is $1
and if i have 2 variables then
$route['product/(:num)/(:num)'] = "catalog/product_lookup_by_id/$1/?2"; Is $1 reffer to first num and $2 reffer to second num?

Yup, a dollar sign followed by a number references the corresponding capture group. Standard regular expression syntax.
:num == \d+
:any == .+
