Sharm would be absolutely fine, though it's changed a little bit recently in that the locals are getting a bit more desperate for trade. Still a good place for some winter sun etc if that's the main aim.
I'd say Hurghada *should* be fine too, but it's a bit more risky than Sharm which absolutely has to remain safe or the country will find itself in even more trouble than it is at the moment, they really rely on red sea tourism for jobs etc.
I would probably avoid Luxor for the moment, not because I think it would be unsafe in itself but if anything is/was going to happen to tourists it would be en route between the big resorts/attractions. Within each locality I wouldn't be remotely worried
