Hidden challenges and "Challenge Accepted" achievement

For certain challenges, for instance "shotgun sniper," they don't show up on your challenge list until you finish another challenge, in this case "open wide!" Can I still finish level 1 of that challenge, even though I can't see it on the challenge list, to count towards the achievement, or do I really have to finish level 5 of "open wide!" before I can get level 1 finished of "shotgun sniper?"

Complete open wide

Sniper shotgun stacks and it will auto retroact. All the ones you did already

Yes. When I completed Open Wide level 5, Shotgun Sniper also went to level 5. I received 266 BA Rank at once.
