I did some fishing in <a class="moz-txt-link-abbreviated" href="http://www.spatialreference.org">www.spatialreference.org</a> with the *.prj
descriptions below, and here's what seems to be the correct CRS for
each of your layers. See below:<br>

<div>I got the shape files from a colleague and am not sure.
Here are the text descriptions from the .prj files:</div>

This is certainly the regular un-projected WGS84 Lat/Lon CRS ,
referred to as EPSG:4326<br>

This file is the unprojected Lat/Lon CRS based on the NAD83 datum,

This data looks like it is projected in the "Web Mercator" which is
described on the spatialreference.org website as SR-ORG:45. The
matching CRS in QGIS would be EPSG:3785<br>
<br>
So you should be able to open each layer individually, and declare
it's CRS based on the above (right click on the layer and select
"Properties->General->Specify CRS"). Now, if you enable
"on-the-fly" re-projection the layers should overlay correctly.
Furthermore, you should now be able to do a "Save As" on each layer
and choose the output CRS to whatever you want, thus creating a
*new* set of layers re-projected to the CRS that you choose.<br>

<div style="word-wrap: break-word;">I am having trouble
with the crs of a particular project which contains 3
shape file layers. I have two layers with display
properly relative to each other, however, I am dubious
that the crs is correct, since they are lat long yet the
scale bar is displaying meters. I have another shape
file, that when read into qgis, does not display
properly at all.
<div>
<br>
</div>
<div>I have tried turning off "on the fly" projections,
loading one layer, then turning on "on the fly" for
the other layers. I have also tried manually setting
the project crs with to one of the layers. I have also
tried manually setting the crs of each layer to EPSG
3174 (Great Lakes Albers). None of these approaches
seems to have any effect on the problem. </div>
<div><br>
</div>
<div>Ideally I would like all files to be EPSG 3174 with
units of degrees as Lat Long. Any suggestions on how I
should be approaching this? Thanks in advance.</div>
