Are the dying trees oaks?  We can't tell because the photos lack the detail needed to be sure.

In any case, it's important to identify the trees and find out  what's causing the dieback. Only then will it be possible to predict whether what's causing the decline is likely to affect other trees in the vicinity.

If the trees are all or mostly oaks, and wilt is present, all are at risk.

Based upon what we can see in the photos, we think the trees are past saving.  However, that's a judgment best rendered by a certified arborist or other tree care professional.

The following publication discusses oak wilt and explains how to find and hire a qualified tree care professional:

I was told that they are Ash trees

thank you for your response above!

Most ash trees in the Twin Cities area are infested by emerald ash borers.  Borers kill untreated ash trees a few years after infestation. Virtually all dead and dying ash trees have been or will eventually be removed.  Emerald ash borers do not harm oaks.
