The first two look like Picea glauca 'Conica' or similar cultivar to me, while the last one might be a cultivar of Picea pungens (e.g. 'Glauca Globosa').
"Picea dwarf" in Google images might get you somewhere on the last one (not sure it is P. pungens). conica is a cultivar of P. glauca; the term "blue" is often applied to distinquish between blue and green cultivars.
