You can view the same information in either list form or task board form, both of which can be shared with team members. If you have a list setup you like (specific columns, filter, and sorting), you can save that as a Shared Tab, which can optionally be shared with others. Task boards are setup in the folders, which can also be shared with team members. You might also want to look at the Dashboards, which can be shared with sets of users.
A Helix ALM project is really a database, so a task board or list cannot report across multiple Helix ALM "projects". If you want roll-up views across different products, you can either (1) store information for your multiple products in a single Helix ALM project/database or (2) use the Helix ALM Data Warehouse component to create a reporting database. Helix ALM Data Warehouse is a free add-on, but is installed as a separate component.
