The second is unused and almost as-new (Grade: 1, $37). The third was never mailed but was folded in half and has major staining on reverse (Grade: 5, $7).  The fourth was also mailed in 1967, with three stamps (two from Tanzania, one from Kenya, when multi-country stamps like that were permitted) and partly legible postmark (Grade: 1, $41).
