as you are landing in the USA from another country you will need to go through US customs,(you wouldn't if you left from minot) it isnt hard tho, you follow the signs and easy peasy, you do need to get your luggage to reenter so that will take a bit
minniapolis is a large large airport (one of the largest) because its a hub for many many other destinations, they do have shuttles and moving sidewalks to speed things up which help, I would phone delta and see what they recommend but im think an 1 1/2 should be enough but not a lot extra, with you kids it would suck to wait the 5 hrs but also suck to miss a flight, hard call for sure especially since you dont know that airport
