As there is some blue showing fruits may not be ripe yet. Maybe try asking with new pictures when fruits are fully colored. Otherwise if there is a local source of information such as a fruit show or a good independent garden center or other plant vendor (ideally a fruit specialist!) then taking several samples there, where they can be examined in person might be the most successful route. Especially if aroma, flavor and consistency would need to be experienced to be able to tell.
I was told that the first 2 pictures may show a Cabernet grape and the second 2 a Reisling? On vancouver Island they probably need till the 14th of Oct to ripen/\.
