Note that this is highly volatile, as Wolf & Levi can make strides in a hurry. Also Gibson can change this in a hurry, by moving on. Elvis' injury is also a factor.
Ingram - Has a starter's job, more or less. That's the volume you want. Team is sneaky better than expected.
Wolf/Levi - Levi has the better situation, as he's not got Markstorm in front of him. Wolf is clearly ready, though. I'd prefer Wolf, as he's a safer bet, but these two guys are in a similar tier.
Dostal - he's got a backup role, at the minimum, which neither Wolf nor Levi have locked down, but.. there is the albatross of John Gibson's contract in the way for him and his team.
Tarasov is last, due to not being in the NHL right now, and having Elvis ahead of him who is not trying to get out of town. Elvis is currently out, so he has an opportunity to cement a backup job.
