Row 4 pic 1 = row 6 pic 2 is not a Ginger but close: Dichorisandra thyrsiflora, "Blue ginger" (but a Commelinaceae and no Zingiberaceae).
Pic 1, 5, 6 are Cattleya, hope there is a specialist on board? Pic 2, perhaps some Encyclia.
Row 4 pic 2: Schaueria calycotricha?
Row 3, pic1: Solandra maxima?
Ruud.
