Hi Riju,
Thank you for your inquire.

1.

Yes, you can buy as many licenses as you want, you can even switch between plans Basic lifetime to Pro lifetime if you have more than 1 client.

We do have in plan to whitelabel the plugin but at the moment there are more requested features from our customers,o I can not tell you precisely when whitelabel will be available. For now whitelabel is not possible with any of the plans.

At the moment there is an option to change the logo for example but this is not the proper solution, because every new update will erase that data and you will need to do it again.

- Just create the .svg images that will be the same size as amelia-logo-symbol.svg and amelia-logo-horizontal.svg, name them exactly the same as these two images, and them replace these two images from folder ../wp-content/plugins/ameliabooking/public/img/ with the images you created.

- You can change this in file ../wp-content/plugins/ameliabooking/src/Infrastructure/WP/WPMenu/Submenu.php in function addOptionsPages(). The image from the menu is called amelia-logo-admin-icon.svg, you should call your image the same replace with your. Also you can change the name of the menu item in this function.

Please note: When you update the plugin, your changes will be lost, so you will need to do this each time after you update the plugin.

Words can be changed using POEDIT or Loco Translate for example very easily. I suggest you to install Loco Translate and then to translate these string.
