It's next to impossible to give a 100% definite ID I'm afraid - it might help if you could provide a close up of a fully open flower and a bud that's showing colour but nowhere near open to decide whether its an HT or floribunda rose, but on current showing, it would appear to be a floribunda, possibly something like 'Mardi Gras' but there are literally thousands of rose varieties, some with only minor differences. Many flowers start out as one shade of a colour and change over a few days to a darker or lighter shade. You haven't mentioned fragrance, is there a fragrance? How many separate plants are in the picture? Height and spread can be another determinant of variety.
