Kick Off Workflow Tasks from a Form
It is possible to "kick off" workflow tasks for more than one user from a form. The HR or Finance person fills in the form and selects a user(s) to send the task to. A task for the workflow will appear on the Task List of the selected users.

In your case, I would recommend that you create a separate form with all the basic information fields in it. Then add a field where the user filling in that form can add the list of users for whom he wants to start the flow. Then create a business rule which uses http.get method to call your workflow URL. You will have to call this URL multiple times depending on how many users you want to create the task for. And you can pass the usernames of those users and basic information data to the flow in this URL by using .
