I have a shapefile that has meters as coordinates, and these do not reference world datums or projections.
Is there a way to assign completely new coordinates to the shapefile so that they align with normal WGS1984 datums and I can open this file along with other maps?
The file I am using is one of the layers from the map on this link:

First, confirm the coordinate system of your data by right clicking on the layer and going to Source. In this case, it shows as the following
To change the coordinate system to match another dataset, use the Project tool, found in Data Management. The important thing to remember is that you need to Project (change the projection) rather than Defining a projection, as the latter will give you the wrong output.
If you already have a dataset whose coordinate system you wish to match, there's an option on the output coordinate system selection dialog box to Import.
