Who just leaves a 747? 3.....with no markings.

Last known owner for all three of those is Icelandic charter company Air Atlanta Icelandic.

Since then, Air Atlantic Icelandic has asserted that they returned the three aircraft to their owner in 2010.

It would appear that AAI had leased the craft from another company, cancelled the lease and deregistered them ; but that the owner failed to paint over the AAI registration marks. The current owners are unknown.

What is the cost for one of those?...

If no one claim them I supposed they will be scrapped since the cost of operating and maintaining one is probably quite high.

They probably have an expired airworthiness certificate, you would have to fly in a set of technicians, get them repaired, get about 200,000 lbs of blue, and two 747 certified pilots, possibly an engineer, and then pay the fees and the scrap value, and they are yours, that is for each craft.  This is not to mention the return tickets for the pilots, technicians if they are from another destination, the cost of getting a renewal on the certificate, and it would also need to be valid at your destination or you could get a fine, and parts, you cannot leave a jet idle for three years and not expect parts to break. Tarmac fees alone are prolly steep but negotiable. 

They might be worth something, the engines alone prolly have value if they are rebuilt.
