It is one of the cranesbills

I think the pink flower goes with the darker leaf top left and is a Geranium? Might the pale leaf be something else?

The pink flower is with the lighter leaf at the front - the back blue flower is Johnsons Blue or something similar. Does the cranesbill belong to the pelargonium family?

Cranesbill is Geranium Cammomile of which I have several. I would question you being able to tell JB from a leaf as I have it and couldnt call it from this?

Yes it does Cammomile

I find this confusing to as Geranium is also the common name of some of the genus Pelargonium commonly known as Storksbill as distinct from Cranesbill.

Common names are confusing...

Yes indeed.

If you look at the top middle bit of the picture you will see a blue flower which is from the plant at the back which may or may not be JB and the leaves for this are at the left top of the pic.

I see it now Cammomile

Just to throw a little light on the subject all three belong to the Family Geraniaceae

Pelargoniums (Geraniaceae) Geraniums
which are summer flowering some are evergreen and they are the ones we usually see grown as annuals.

Geraniums(Geraniaceae) Cranesbills
These are Perennial plants often evergreen and can be fully or half hardy meaning they need to be sheltered from frost.

Erodium (Geraniaceae) Storksbill
Mounds of often evergreen hardy or half hardy perennials. Often smaller than the Cranesbills and suitable for rockeries.

Thanks for that SG, I grow varieties of all 3 and still find it confusing.

Me too which is why I looked it up. I thought many moons ago that regal pelargoniums must be perennials but they are one of 4 or five different types which are grown as annuals and brought in to the house to over winter if you are keen. I had to bone up on a lot of plants when I was the local Flower Show secretary because I was expected to know everything. Some of it sticks.
