David, are you in the UK? Citrus fruits don't grow outside here, they need a warm conservatory.
It's not a native British wild flower, it comes from North America and is a member of the Asteraceae family (daisy).
How about Ligularia palmatiloba for no. 1?
3 looks like a Spirea, also Lonica nitida.
4 is a Hebe.
5 could possibly be an apple.
I'd go with Lime (Tilia) for 6.
No idea about no. 1, off to do some research!
Just to keep this straight, Bird Cherry (Prunus padus) has black fruits, not white.
I think the plant in the OP might be Spindle, Euonymus europaeus. If so, it should have striking orange and pink fruits in the next couple of months. When was the photograph taken?
Which plant, the Hebe or the Potentilla?
I agree. Don't try to keep it in a pot though, it won't thrive.
A Sedum, I think.
The second one looks like an Inula.
