One very common reason why the lights in a room don't turn on when you flip the light switch is this: when an old light bulb fails - this usually happens just when you switch it on - the excess current causes the lighting circuit's circuit breaker to trip to shut off the current.
To get the other lights to come on you must locate the tripped breaker in your breaker box and turn it back on.
The old light bulb can then be replaced - but, before you unscrew the old bulb, always remember to switch off the lights off first!

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
