The Redbox pics on Миниатюры 1/72 site look like Russian War monks, then on the right -top to bottom -Turkish sailors in battle, Turkish janissaries(yeniçeri), English sailors in battle.
The English sailors look more like 16th century though some may do for early 17th century. Fashions change quite considerably in the 17th century but working clothes like simplified doublets outlasted most of their owners and were often recycled and slightly modified. The paintings by 17th c Dutch artists of maritime scenes are excellent reference material. The captain looks more characteristically Elizabethan and would be a bit of a Don Quixote if he dressed like that in the mid 17th c.
