Currently, the Windows operating system does not provide a solution to create two mouse cursors which can be independently controlled, nor do they have a solution which allows the cursor to be controlled differently based on two independent mice. There are a few open source solutions that claim to be able to provide some of the functionality you require. If you would like to try one of these solutions I would suggest that you Google 'multiple independent mouse cursors'.
