Egomania is basically intolerably self-centred. In a more technical sense, it's an obsession -- an obsessive preoccupation with one's own self, usually in the form of following own impulses and have delusions of grandeur.
Megalomania is a rather loose term, and usually means have delusional fantasies of omnipotence (having unlimited or very great power, whatever 'power' might mean to that person). Interestingly, megalomania was the standard term for narcissistic personality disorder before the 1960s (so far as I recall from my psychology degree over 30 years ago).
Responding to conflict with confrontation will just lead to more and more arguments with peers, family members and loved ones. People will start to avoid the friend because many people do not like confrontation and prefer to deal with conflict in a calmer more understanding way. The friend needs to take that approach in order to sustain positive relationships. The calmer the approach to conflict the better. A mutually supported understanding needs to be reached in conflicts in order to resolve them peacefully. Aggression and confrontation just leads to more anger and upset.
