fruit bushes and fruit cage help

right, trying to not make things complicated, and as my polytunnel flew across the garden last night, i guess now is as good a time as any to plant my fruit cage.

so i need to know some things (having never grown anything more than one strawberry plant)

i have approximately 15 raspberry bushes, 3 of each type (i like raspberries)
3 blueberries (yup i know these need acid soil, i'm working on it)
3 redcurrant
5 of 2 types of blackcurrant
3 blackberry
various strawberries

and am hoing to grow from seed
a couple of melon pears
dragon fruit
gojiberries
cape gooseberry
and whitecurrants

sooooo ...... how do i plant them so that

1 they get the best chance of growing decent fruit
2 they take up the smallest amount of space (so i don't have to dig up the whole lawn)

basically what's the minimum distance i can plant them apart ..... the allocated space is roughly 2.5m x about 9m but i can make it bigger if i absolutely have to

the place i have planned is south west facing, but there is a fence to the west, so the sun goes over about half of it by about 2pm, from early morning.

i have 5 of those arches for growing climbers up, and plan to cover the whole thing with netting so the birds can't get in, which also means i can suspend wires across between them as support for the plants that will need it.

so what is the minimum space needed by each plant, and how big do they actually grow??

can i plant the strawberries and other small things between rows, or will that not allow enough light?

HELPPPPPPPPPPPPPP!!!!!!!
