Answer 1

You can use following steps:

1. Pass input user value from your html form to Activiti using taskService.complete(task.getId(), taskVariables); taskVariables should contain variable with keys for example 'userId' or 'userIds' to access submitted values in process instance
2. Use expressions in your process definitions or to assign tasks
