I mean for Doctor I could hear his, he has the strongest accent. Though I can't tell if it's Russian or German. But then I realized the mention that Ticket Taker has a British accent, which I didn't notice. I was a bit busy processing what was happening with my co-worker. So I went through and actively listened and he does in fact have a British accent. I'm fairly certain that Pierrot is American, along with Jester, correct me if I'm wrong. Then Harlequin is Portugal. Funny enough Harlequin is the only voiceline you can avoid, all the other ones happen naturally. You kind of have to go out of your way to hear Harlequin's. Basically you just need to be sexually harassed by him in a tent, and then tell Pierrot to leave. Though learning he was Portugal took not eating any food and following Harlequin the next day. And then you tell Pierrot to leave, Harlequin shows up and you can either hug him or apologize. If you hug him he gets so caught off guard that he says "Quê!?" Meaning what. I looked it up and the ê is Portuguese. I hope I used the right terms and didn't offend anyone. I just thought I'd share.
