I don't think so - its not really set up for doing inter-layer references. I wrote a few lines of python that will do it though (assumes you have two layers loaded with names a and b in the layers list:
reg = QgsMapLayerRegistry.instance()
a = reg.mapLayersByName('a')[0]
b = reg.mapLayersByName('b')[0]
collection = {}
index = QgsSpatialIndex()
for f in b.getFeatures():
index.insertFeature(f)
collection[f.id()] = f
with edit(b):
for af in a.getFeatures():
p = QgsPoint(af['lon'], af['lat'])
box = QgsRectangle(p, p)
for key in index.intersects(box):
feature = collection[key]
print feature['name'], af['name'], af['lon'], af['lat']
feature['name'] = af['name']
b.updateFeature(feature)
Just paste that into the QGIS python console and it will update the name field of b with the value in a for the places where the attributes lon, lat in a intersect b.
Please test in a sandbox before trying on your production data....

Dear list
can anyone advise whether the NGI 50 cm colour orthophotography is available as a WFS in QGIS?
Kind regards,

Do you mean WMS? If so you can use this unofficial URI:
http://aerial.openstreetmap.org.za/wms-ngi-aerial
I'm not sure if it has the most current imagery in it though - grant slater from OSM could probably comment on that...

Hi Tim
thanks, yes I meant a Web Map Service.
The website you sent gives the following error "mapserv(): Web application error. Traditional BROWSE mode requires a TEMPLATE in the WEB section, but none was provided. "'

Just open QIGS, (or your *cough* other GIS app) and add a new WMS connection using that URL and it will work.
