The fish would be easier to ID if one or two were in the palm or your hand. From the distant images of your minnows in Pic 3 they look like female FHM full of eggs. Picture 4 sure looks like a female mosquito fish.
At this point in time for the crayfish, I do not think the population numbers are abundant enough to cause any turbidity problems. However they could suppress plant growth especially if there is not FA for them to eat at the crayfish habitat. After the 1st and 2nd crayfish reproductive seasons (all have young in spring) there could maybe enough crayfish to cause turbidity - it all depends. A lot of it depends on what fish and sizes are present and amount of cover for the baby crayfish. Northern crayfish (NC) are larger and somewhat more aggressive species compared to papershell crayfish thus NC juveniles and adults of large sizes can better avoid predation from smaller and even medium size bass predators. Old Northern crays can get 2X the size of papershell.
