The top one is a Bristol Freighter that used to belong to Hawk Air (I saw that particular one on its final flight, actually the last fight of a Bristol freighter, on its way through Prince George to the museum where it now resides)
The bottom one is a Grumman S-2 Tracker, modified for fire service.
The very first model of airplane Cessna produced, the O-2 and an Avro Arrow is stashed away in the back room out there, interspersed between acres of farm equiptment.
