The two States of Sonora and Baja Caliifornia, Mexico share a border with the state of Arizona. California and Nevada share a border with Arizona that is marked by the Colorado River.

Partly, yes.
Bolivia and Brazil share a border.

Yes, it's the same country.
Denmark isn't an island, Greenland is. True, Greenland belongs to Denmark, but there is a big difference between the country Denmark and the island Greenland. Danish isn't the same as Kalaallisut (Greenlandic.) Greenland is the largest island in the world, not the third largest.
Florida and Alabama share the same border for a short distance.
The land of the Danes, so Denmark... but not the same Denmark as today.
Jamaica is an island nation which does not border any country. Borders are for land-based crossing from one country to another, like the United States:Canada. Haiti and the Domican Republic are island nations that share a land border on the same island of Hispanola. Jamaica may have territorial waters that border other islands' territorial waters, but that is not a true border in the sense intended by the Questioner. Canada borders Greenland this way.
