Shoutout to the incredible looks a lot of the background characters were sporting in the Republic of Pirates. I'm pretty sure the ones in the 7th and 9th screenshots are Spanish Jackie's trans husbands.
As a bonus, I think the woman in the first picture is also one of Jackie's husbands?
That's her in the scene where Jackie waylays Stede stealing the chest of indigo. When they leave, Jackie says, "Let's go, husbands" to the whole crowd.
