In a word: no.
Italy and Ireland do not have the same flag. Italy's flag is green, white and red, arranged in three equally-sized vertical bands. Ireland's flag is green, white and orange, arranged in three equally-sized vertical bands.
Same as the normal France one.
The capital of Italy is Rome therefor it should be the same however Rome has its own flag partly to do with the fact that the north and south of Italy don't talk and are divided by Rome the flag is :
both have the same population
The same as what it is now
Italy's flag is a tricolor (green, white and red) Vertical flag
Japan Great Britain Ireland Wales Scotland Italy Germany France Spain England Poland Jamaica Greece Cuba
There are no stars in France flag.
The Italian flag

The same as in UK, France, Italy, Germany or anywhere else.
