Updating Master Sheet across forms



I am creating several forms that must link and update a Master Sheet. The Status column must be updated as the process moves through the forms. Is there a way to link the current status on the Master Sheet? I know it can be done, but since it involves several forms I would like to know if there's a way to do so.

Also, is there a way to duplicate rows based on a field entered on a form? For example, if in the field 2 is selected, the row will be duplicated.
