The white flower is a Hibiscus but I'd be interested to know what the other one is.

it is similar to a house plant called tradescantia could it be a relative?

I think the red one is a very poor Lonicera tatarica Hack's Red, except that is not really a climber, it is a tall shrub. If this is a climber then have a look at the red flowered versions of Honeysuckle.

I wonder if the top one is Jasminum beesianum? The flowers are small and pinky-red and it always looks sick in my garden.

I also think the top one is the jasmine. mine grows lots of foliage and the pinky red flowers are small and therefore not as good as I'd like.
the bottom is an hibiscus as already said.

Looked again and the ladies are correct.

Thank you for all your help much appreciated
