Yes and No.
Garden of Venus is essentially meant to be a different "world line" where things played out quite differently, so while the girls share looks and core personalities with their counterparts from previous titles, what's canon in Garden of Venus isn't canon in the previous smaller games and vice versa.
My Naughty Neighbor and Mia's Bad Hair Day were originally meant to be part of an episodic series of small 'Venus Stories' and play in a more 'normal' world than GoV. The focus of the Venus Stories was meant to be more on the girls and their (dirty) adventures, rather than some male protagonist, so pretty much a series of short and lewd kinetic Visual Novels that would've covered different kinks than GoV will.
We might revive the concept of the 'Venus Stories' one day, though we're not sure how successful the concept would be, since most people prefer the classic harem experience.
