Good Evening Joe, 

I believe the first photo is turf grass. The second and third photos appear to be crabgrass. 

I am attaching a link to the U of M Extension Yard and Garden website on grass/weed identification which may help:https://apps.extension.umn.edu/garden/diagnose/weed/grass/index.html

Here is another link about annual grass weeds:https://extension.umn.edu/weed-identification/annual-grass-weeds#foxtail%2C-yellow-826815

If, after reviewing the website you believe it to be crab grass, here is a link to control crab grass in your lawn: https://extension.umn.edu/yard-and-garden-news/controlling-crabgrass-your-lawn

And, here is a link to the lawn care calendar: https://extension.umn.edu/yard-and-garden-news/minnesota-lawn-care-calendar

Hope these website links help with your weed identification. 

Good Luck!
