first step: have a look at their metadata with "gdalinfo <filename>"
check that is all in order.

if projections are all the same use r.in.gdal from the new location to load in the other maps. If they use different projections you can use r.proj to move them into the same location. each different map projection needs its own location.

qgis is a nice data viewer if you don't want to create new grass locations just to look at the data. (www.qgis.org)
