I had 6 crowns on the front one of them had a hairline cracked. Must I replaced all of them?

Can it be repaired? Or I had to replace the new crown.

If you have six crowns then you would only replace the damaged one. If you have a bridge that is replacing six teeth then you will probably have to replace the whole bridge.
