9 and 5 are the ones who will still be good major league players if your projections are off by a few points across the board. Take one of them, or go with hockey1984's plan.
DO NOT TAKE 7. That 25 is his durability, not his health; he'll be able to catch about once-twice a week before he starts to fatigue and play worse, and/or get hurt. Furthermore, you won't be able to get him enough playing time to develop him to his"real" projections, so he will be even worse than you think when he gets to age 27. He's not a bad pick for late round 1 or round 2, but not at pick 4.
