First story from Tendo-ke no Musume-tachi Vol. 1, English transltion by DarkAsh here. Second story is also from that doujin, but for some reason was redrawn even, changing the male character. Maybe the Italian(?) team had a thing about father/daughter incest (but apparently they were ok with sister/sister...). Third story is from LOOK OUT 20 (if it was also published separately, we don't have the RAW scan for that) and has also been translated here
