According to the commentary, these are the fast cruisers under the command of Tsuboi Kouzou during the 1894 Battle of the Yalu River.
The front ship is the Yoshino but beyond that it's tricky, given a front-on view. The Akitsushima is probably the third based on the bow. Naniwa and Takachiho are nearly identical so I can't really differentiate between them.
