Does divorce occur if the words "you are divorced" are uttered twice in a state of extreme anger, and is it considered two divorces or one, given the husband's regret and his claim of not being conscious of his actions?

The divorce pronounced by an angry person who does not know what he is saying does not take effect. However, if he knows what he is saying, his divorce does take effect because he is held accountable. If your husband had no control over his utterance of divorce in either case, his divorce would not be valid. However, your statement contradicts the lack of awareness by mentioning his intention. It is best for your husband to speak directly with a scholar. Assuming the divorce has occurred, the number of consecutive divorces without an intervening reconciliation is two according to the majority of jurists, while some scholars hold that it is only one divorce. Spouses should exercise wisdom and reason when facing problems and beware of anger.
