Hello,
You can load a vendor using the HikaMarket core :
if(!defined('HIKAMARKET_COMPONENT'))
include_once rtrim(JPATH_ADMINISTRATOR,DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR.'components'.DIRECTORY_SEPARATOR.'com_hikamarket'.DIRECTORY_SEPARATOR.'helpers'.DIRECTORY_SEPARATOR.'helper.php';
$vendorClass = hikamarket::get('class.vendor');
$vendor = $vendorClass->get( $vendor_id );
You can otherwise use a SQL query to load a bunch of vendors directly in the hikamarket vendor table ( #__hikamarket_vendor ).
To get more details about HikaShop triggers and database structure :

Please note that your request is related to custom development ; it requires some PHP/Development skills.
Custom development is also outside the limit of our support but you can contact some of the HikaShop partners :

Regarding your second message :
1 - It requires view override and custom development regarding HikaShop product page. Major part is related to HikaShop and not HikaMarket.
2 - Same as point 1.
3 - I'm afraid that's related to HikaShop and not HikaMarket.
Regards,
