Here's my guess for the first one. I haven't played Klax in ages. Drop two rusts in column 4, two in column 5, and then one more in column 4. That will get a diagonal that removes the rust in column 3. From there it should be easy to get a horizontal. I thought I had a solution to #2, but the wilds make it difficult. And #3 would be too hard for me even if the game weren't cheating.
