The first picture (011) is one of the common, smaller hoverflies; Melanostoma scalare. The fact the eyes aren't touching shows its a female and the white "dust" patches on the face are useful in distinguishing this species. We now think that "M.scalare" is more than one species, the NHM is doing some DNA analysis to answer this question.
Pictures 008 and 004 are Muscid-like flies, so related to the archetypal "house fly", but with nearly 300 UK species this is a fairly diverse group with a range of life-strategies.
The last picture (001) is a classic bluebottle. A member of the Calliphoridae which includes the greenbottles and cluster flies. This is a much smaller family in Britain that's just shy of 40 species. There are a couple of common and widespread bluebottles, a view of the face and "jowls" is the best way to tell them apart.
These look like Syrphus ribesii (004) and Eristalis pertinax (001 & 003). However, there are similar looking hoverflies to these species; a clearer view of the leg colouring would help to confirm the ID in both cases.
@Cuileag I'll try and get more of each next time. I tend to take a photo every inch or so as I sneak the camera up to them. They normally dissappear before I can get different angles. I think its because of my obsession of trying to get as close as possible then the camera nudges them! Thanks again for the ID'ing
@Lewis Heres another photo of the spider on his own. Im not sure if he was sneaking up on the hoverfly when I took this. The fly didnt seem over bothered. Probably the entire lack of camo. The photo was taken on a car park siding that consisted of dandelions, nettles and overhanging flowering shrubs from a garden (dont know if that helps for identifying him?). The photo is abit closer and abit clearer.
