Yes, there are. You can find some on popular fanfic websites like FanFiction.net or Archive of Our Own. Just search for 'Star Wars Male Exile Surik' and you'll likely come across various stories with different plotlines and interpretations of the characters.
There are indeed good ones. Some fanfics might focus on the Male Exile's adventures post - his exile, with Surik playing a significant role. They could explore his relationships, his journey to regain his former self or powers, and how Surik might be involved in that. It really depends on the creativity of the fanfic authors. For example, one fanfic could have them team up to face a new threat in the Star Wars universe that was previously unknown.
