Problem:

Now I would like to know if these additional fields should be present in user profile (in case of "Customer" role) or it should be in Customer under Woocommerce?

Solution:

For the customer user role, there are lots of custom user fields from Woocommerce plugin, for example:

billing_address_1
billing_address_2
billing_city
billing_company
billing_country
...

If you are using Toolset user form, you can try these:

1) Dashboard-> Toolset-> User Forms, click button "Manage non-Toolset User Fields", here you can find and enable those custom fields.

2) Edit/create your user form, then you will be able to put those user fields into form content.
