There are a wide variety of soils in the Lafayette area.
However, none of the soil series symbols you posted (Ce, Gn, Su, HeF, and CbA) appear to exist in the Tippecanoe County Soil Survey. Are you certain you have the correct data for your tract?
These symbols can/may apply to more than one soil series in the state, this makes it difficult to answer your question. I'm on the other side of the state, in my area Ce is Celina (approx 24" to seasonal high water table an approx 48" to compact glacial till), Gn might be Gennesse (a well drained floodplain soil), and HeF (is likely a Hennepin on 25-35% slopes, steep well drained, shallow and eroded). This may not apply to your site.
Again, double check to see what soils are mapped on your tract, as none of those you've listed appear to be in Tippecanoe County in either the printed or online soil surveys.
