Hi,
1 - In the menu "HikaMarket > Accesses > Vendor options", you can configure different limits for different Joomla groups.
Then you can assign groups to your vendors and they will have ACL & Restrictions depending these groups.
2 - You just need to not let your vendor manage the payment methods.
By not activating the edition of the payment/shipping plugins or by removing the corresponding ACL (payment).
3 - By creating a shipping method without any vendor assignation ; your shipping method would be available for every vendors.
