Languages as in one of the love languages, like touch, words, gifts, acts of service, admiration, spirit rises, and quality time; not real world languages XD

But to the actual questions; it'd be like the personification of Words hanging out with the personification of Wrath, or the personification of Touch hanging out with Lust.

It would be people that represent the language/sin.

What constitutes as redeemed is once they don't act on the urges that their respective sin brings... So Pride, for example, would stop being haughty and arrogant; instead being at a good level of confidence. Envy wouldn't be as overly jealous. Greed wouldn't be a kleptomaniac that believes everything should belong to them. Gluttony wouldn't binge-eat as much/as often. Wrath wouldn't freaking kill everyone for glancing at them the wrong way. That sort of thing.
