From what I can see, there's only one proper island village here, the coordinates of the second one you posted are on the mainland, as is that Temple.
That said, it looks to me like that second village is also right next to a jungle with several temples in it, and the ocean also has shoreline access to a mesa, snow biomes, and if you're willing to go on a bit of a voyage there's a witch hut. Several other islands of varying sizes that you could theoretically set up multiple players on, including Roofed Forest, Birch Forest, Mesa, and Flower Forest/Sunflower Plains Islands.
Solid Archipelago style seed, with a good selection of mainland biomes to cherrypick from if you want.
