Yes
Regular pocket camera yes! Not a professional interchangeable lens camera. Also no selfie stick
Depends on the event
Each event is different. It's worth taking it, just in case! Katy Perry asked everyone to turn their phones on Flashlight during 1 song. You never know; so be prepared!!
Each event is different. They post what you cant bring in at the door. Most concerts don't allow cameras.
The general answer yes just don't broadcast at all or else they'll catch you
A regular camera yes A video camera no
For most events, you can. However you could never bring a long lens or professional cameras.
