I don't remember if I mentioned the Star Wars analogy before, but here it is.
I think Bucky will be Darth Vader. Sinister, prominent, and with a connection to the hero that leads to his eventual redemption.
Zemo, Lukin or Strucker will be Emperor Palpatine. A true, unrepentant villain who drives the Vader's actions, and is ultimately responsible for wrongs done. However, he is less visible.
Crossbones will be a little like Tarkin, in being of comparable station to Vader. But mostly he'll be Bobba Fett, in receiving no true character development and just being intimidating and looking cool, but hopefully he gets to do something interesting.
Zola? I think he'll show in flashbacks.
