Hi,
I'm not able to understand your issue.
On one hand you say that you cannot approve the products but on the other hand, you wrote that you can see the 6 products in the HikaShop product page.
When a product is not approved, it's not a "product" for HikaShop so the page is not available.
If your vendors do not have the "product / approve" ACL ; when a product is created, it will have the special "waiting approval" product type.
All products with that product type are visible in the HikaMarket backend, under the menu "Products to approve".
In the backend, you do not have any restriction like in the front-end (where you need to have the "product / approve" ACL).
Can you please detail what data you have and what exactly is your issue ?
Few screenshots could help to understand what is the problematic point.
