it's going to be very difficult to name these roses as we have no idea what ones would even be available in Bangladesh. Can you give us any information about where you bought them and what types they are?

Thank you for replying....actually they are sold in a very retail style the seller dnt know the names either or the type of plants ...guess my flowers would be nameless :(

The red one looks a lot like IMPATIENT. And the cream with pink edge looks like HELEN NAUDE.

The flowers od roses can be diffrent depending on weather conditions, a season of the year, soil and fertilization. That's why besides the flowers you should compare leaves, shoots and thorns - they never mislead.
IMHO, the flower of rose 1 is very chararacteristic of "Chicago Peace" ( Hybrid Tea, Stanley C. Johnstone, USA, 1962). The shoots of the variety are reddish. In my garden...

The rose 2 with the red flowers might be one of the fifty similar. It is also HT.
It is much easier to indentify the next rose and it is most likely "Double Delight" (Hybrid Tea, Swimm & Ellis, USA, 1977). In my garden ... (I have just seen your previous post with the pictures of bi-color rose, they are closer to "Double Delight" than these ones here)
As the flowers age, the color red begins to dominate and this occurs through the interaction of sunlight ultraviolet light on pigment found in the petals. And that means that you never have the same two flowers, because solar conditions are variable and exposure time. This also explains why 'Double Delight' grown in greenhouses, where UV rays are filtered out, remains the pure white rose. Both roses are very popular all over the world, no matter where you live. I grow them in Poland, USDA 4a, under cover during the winter.
