Do the Exit signs light up? Or are they always lit up during a flight?

They have a battery backup. They will light up if the electrical power fails.
I'm not sure as to their normal operation.

Do the main cieling lights remain on?

Depends on whether someone shuts them off and whether you loose power.

Do the passenger lights (above the seats) remain on?

Depends on if power is lost.

Are the emergency floor lights all one colour? or are they colour
coded in some way to guide passengers to the nearest exit?

They are all the same, there are several close together to indicate when you
actually reach the exit row.

Also, are there any alarms or announcements that are made during an
emergency?

No alarms. The flight crew/cabin attendents will make announcements.
