Nr 1: Ok-ish start but nothing great. Maybe a bit food-poor longterm, though that applies to nearly all starts. Like Sengir said probably best to move settler 1W for another city on the east, but move warrior 1NE first to see what's there.
Nr 2: Yikes! Only 2 calendar resources for food, jungles nearby. Nogo!
Nr 3: Only corn, but that probably means there's metal or horses in the bfc. I think there's a minimum of resources each start has and it's definitely higher than 1. Somehow I think this one might have the biggest island of the 5 starts. But you never know, of course.
Nr 4: Good food, think there must be another hill N of western clams, read somewhere that each start always has 3 hills minimum. Room for city on southern tip on E wine sharing clam and rice with capital. Maybe consider move capital 1N of current settler position also on wine (maintains all the food) to have 2nd city on forest 1S of rice.
Nr 5: Gems rock of course, but clam+cow is not much food longterm like 1st start. Have a feeling this island is tiny...
I did some rolls with these settings yesterday and the chances in any case are quite big that we end up with an island with room for just 2 or 3 cities.
Preferences? Probably 4 and 3. 3 is a bit of a gamble but I think something nice must show up, either metals/horse or some extra resource in the 2nd ring east or north. Or both
