I agree that 3rd street should be a reraise.

For 4th street, if the hands were random I'd say a clear call because the EVs are split and you are still the favorite to scoop. However, you red flag should be the reaise from the 9. What doesn that say? A pair of 9s at least? A three straight that is now a 4 straigt? A little opponent knowledge would be good here but a fold is definitely called for if you think they have a pair of at least 7s or a 4 straight as that would put you last in the pack.
