One wing is just the standard for Ukaku types. It's like how Kaneki and other Rinkaku types gain more tentacles as they get stronger, Ukaku gain another wing and plumage. Touka simply wasn't strong enough to get a full second wing (though she has a partial one). We just didn't see very many one winged Ukaku to compare. Banjou also only had one wing.
