Carbon V stuff is pretty collectible, as it's been discontinued for 15+ years, and was made in the US. And with yours all appearing to be NIB, you should be able to get top dollar.
The Mini Kukri is the rarest of what you have there, so would be the most valuable to a true collector. Don't see any recent similar sales on ebay, but would expect $300+.
For the Kukri, there were 2 recent sales on ebay for $290 each.
For the Recon Tantos, sell prices on ebay are all over the place, but would expect somewhere around $150 each.
