The two large knives are khukuris. From Himalayan Imports:

The one on top is a 20 inch Ang Khola (forward balanced chopper) made by Sher Bahadur Bishwakarma of BirGorkha in Nepal. The bottom one is a British Army Service model also made by Sher, 15 inches long, designed for general purpose and combat.
They are both very functional tools, and could serve as excellent weapons if needed.
