The Red giant flower looks like Rafflesia_(flower) but if I examine the petals clearly it's more likely a red sunflower without its stem.

The White flower with yellow stamen inside is called Lily of the Nile, Calla Lily, Easter Lily or Arum Lily.

The blue small flower has the appearance of a Scarlet Pimpernel.

The round white yellowish one looks a bit like dandelions.

I'm note sure about the round red and blue flower, the larger white flower and those small white flowers hanging above.
