Hi,
The profile edition page is a Joomla page. And Joomla has no mechanism to allow us to add a return button on that page. That's why there is no return button there. To add one, you would have to create a view override of the Joomla user profile page and add custom HTML for the button.
To remove the "customer account" button from the HikaShop user control panel, you can just disable the "HikaShop joomla user account link plugin" via the Joomla plugins manager.
For the addresses button, there is no option to remove it, but you can hide it easily with a bit of custom CSS you can add either in HikaShop or in your template:
.hikashop_cpanel_address_div{ display: none; }
