First, Remember that audiences are not, never have been and never will
be security.
Based on that there are basically two possibilities for doing what you
request. Neither is particularly easy because SharePoint doesn't make
any provision for views to be secured, only lists and items in lists.
1) create the views that don't filter the library as personal views
while logged in as the individual user. This will work, but is very
tedious.
2) Set security on the individual form list items so that only a
group (those who should see the whole group) and the creator of the
form have access to the item. To do this going forward you will want to
create a ListItem event handler to set the security of an item when it
is inserted. This requires programming, but it's the best way to do it.
