Cosplay request for the 3rd panel, and copyright request for all of the apparent references in the 3rd and 4th panels.

Panel 3 cosplay on the right looks like Emeraldas from Harlock Saga.

The red ship on panel 4 appears to be the Bentenmaru from Miniskirt Pirates.

What? No Space Yamato?

The blocky, white vessel is the Turtle from Space Adventure Cobra. Adding copyright tag and initiating "Turtle_(ship)" tag.

Yamato's not a pirate ship.

The thing with the bird-head beneath the Viking-ship is Dola's ship from Laputa. What's it's name?
Is the Viking-ship from Chiisana Baikingu Bikke?

That was before translation, but now that you mention it, how about the Outlaw Star?

Uhhh, they're not pirates. Their enemies are definitely pirates though (Kei Pirates).

3rd panel: New Arcadia from Waga Seishun no Arcadia - Mugen Kidou SSX (sequel to Uchuu Kaizoku Captain Harlock)
4th panel: Old Arcadia from Uchuu Kaizoku Captain Harloci, the right of it is Queen Emeraldas, Emeralds's personal starship and of course the right most is Bentemaru from Moretsu Pirates
