Cool
Lessee, majority of these Taiwan (& all sound like titles that's been IDed from old 'Cinemart' issues heheh). Anyway I'll start with the easy one, 'Love for Sale'. My guess is this is dtr. Wu Chia Hsiang's last or next to last (same period as 'Price of Love', 'Long Years') Romance/comedy. Paul Chin/Shu Pei tells me Shaw of course. Just verified that Shaw Screen has it listed as 'Love Auction' but I remember seeing it in SS matching your primary English. BTW, they have it as 1971. No related staff comes to mind (yet).
Survey sez: 愛情大拍賣
(Mando pinyin: Aiqing da paimai', Canto: Ou Ching dai pak mai)
Give me some time on the others, they're a lot harder to ID....to be continued.
