It's almost totally random, but there are reasons for individual classes. The Fubuki sisters must become classmates because there are 24 of them (counting the 4 Akatsukis), so that the age difference between Fubuki and Inazuma will become too extremely big to keep Fubuki as the semi-loli she is. This is the deal for all destroyers because there are yoo many of them.

Relationships between CL classes are similar with the exception of the three Sendais, probably because there are only 3 of them. Relationships between other ship classes tend to follow specific rules related to the histories of each class. For instance, the Myouko class is depicted as sisters even though there are four of them. This is because they're actually two pairs of fraternal twins (Myouko and Nachi + Ashigara and Haguro). Similarly for the Kongou class, Haruna and Kirishima were also twins, so all four are sisters. However, Atago considers Takao her elder sister despite both (and Maya) being finished on the same year. However, Maya and Choukai form their own sister pair independent of the first two. This is because Maya and Choukai ended up being similar to each other but different from Takao and Atago after modernization. They're very easily distinguished due to different bridge shapes (which is also why they wear different uniforms).

The Mogamis are a curious case because both Suzuya and Kumano consider each other and Mogami as sisters but Mogami and Mikuma are just friends. Historically, Suzuya was Kumano's elder sister, but she, Mogami, and Mikuma were finished in the same year. There's no real way to explain these sisters' relationship.

Ise and Hyuuga are sisters and depicted that way in the game. Hyuuga's constant complaints about being sisterless is a game in-joke because she's depicted to be much more mature and elder-sisterly than Ise, who's actually the elder sister. This is similar to the relationship between Tenryuu and Tatsuta. In the official Fubuki Ganbarimasu 4-koma Ise and Hyuuga clearly identify each other as sisters, with the caveat of their inverted relationship.
