No, user cannot decide what Roles they are in, they are automatically in all the rules that they are in.
However using dynamic form rules the form could behave differently depending on whether the current user for example is has their user ID in a particular field. So for example if I am the designated Project Manager for a Project record the form could behave differently if I was just the Admin Assistant userid in the admin assistant field.
