Promise you won't get angry at me?/

Amate gazed over the new land he claimed as his own. It was small, perhaps a mere thousand feet from shore to shore. It had some good qualities, however. Its surface had a few groves of trees, and its slopes were mountainous, with plenty of available obsidian and basalt. However, it had one great characteristic: Within its summit, hundreds of feet above the waterline, was a warm rumbling. Amate had heard of these isles of fire, and now lived on one.
The nearest islands were to the south and the east, both about 150 miles away.
Robert gazed to the west at the small, rocky island he had passed while trying to find a place to live. Their options were limited, but their choice good; they were on an island about 5 miles across and covered in rich rainforest. They heard the call of a strange bird, larger than any they had heard ever before. The nearest islands are the western one, 150 miles away or so, and ones to the south-southeast and the southwest, about 200 miles away each.
Matta had less hope than the others. Another tribe had wiped his out to these last dozen and a few children. His isle has low and had a lagoon excellent for gathering shellfish, but given its small size (about three miles long and one wide), hunting would be limited. Still, if others could be avoided, maybe Matta's future was bright. The nearest islands were to the north and south, each about 150 miles off, with other islands to the northeast, east, and southeast only 200 miles off.
Maya fled to a small island to escape his past and steal his future from...something. His island was only half a mile across, but it had forests of mangroves from the coast to the swampy interior. Only a few hills in the center were dry. On one hand, dangerous reptiles lurk in the swamp; on the other, exotic and tasty reptiles lurk in the swamp. The nearest island is about 75 miles to the southwest, and much larger, but less secluded. Other nearby isles are 150 miles to the east and west.
Raith made his home on a sandy isle about six miles across. A larger and clayier hill has a spring and grass, but little else is present. Thankfully, there are plenty of burrows, indicating a large amount of small game, and the shores teem with shellfish. The nearest islands are 100 and 125 miles to the northeast and the mostly-east.
Nerjin found an excellent place to raise his children. It was an island, over ten miles across and covered with jungle and sheer cliffs. A river valley makes a good first shelter, which will be vital given the deep bellows Nerjin heard...There are several islands within 100 miles, which I will write briefer descriptions of later if asked.
Kamehameha prayed that the gods would forgive him. He had failed. However, perhaps he still held the gods' blessings. He had landed on an island he hadn't been able to guess the size of--dozens of miles across, that was certain. It was, however, almost entirely sand and water, with some hills sporting grasses popping out here and there. The pools supported abundant shellfish and octopi, but pickings will be slim for agriculture and other botanical foods. The nearest islands are 150 miles away or so, to the north, south, and north-northwest.

That should be everyone. I gave everyone an island, rolled for traits, and fiddled with the results to make it more balanced. For instance, TopHat was supposed to get a small island which would be a glorified sandbank. I improvised a bit.
I suggest trade. Once you get settled, try lighting smokey fires and sailing to other islands. Maybe you'll find another player willing to give you what you want or unable to stop you from taking it...
