Here's what rosalind Creasy, author of edible landscaping has to say about strawberries.

The alpines can get by on a little less sun so they are more likely to do well under the shade of another plant.
Most strawberries actually prefer a container or a raised bed. As for companions for strawberries borage, and lupins have been suggested. Lupins wont grow for me. There are a number of options shown in the Creasy article.
One consideration for the raspberries is that they will need a whole lot more pruning, tying, and care than the blueberries. Also, don't they have thorns? like blackberries do. So you wont want them too close to the blueberries to allow for blood-free harvests.
Also -- where are you? Blueberries in the south are 8 to 12 ft shrubs.
