maybe they are not the registered names for them just names given to make them more marketable its a bit like dogs they often have a name that indicates the breeder so there are a number of roses for example with kordes in the name... of course there are plenty with pretty names...where did you get them from?
Angel cream ? floribunda but there is a rose called Angel but it is listed as a florists rose so grown for long stemmed cutting flowers might be a multiflora florist flower though so would look a bit like a floribunda as the flowers are carried in sprays
Hotel Royal and grand hotel are both reds but neither are floribundas
