What plants can we use in a walnut guild?
There are plenty of plants not affected by juglone that we can use in the food forest.
Toby Hemenway described an interesting plant guild for a walnut tree in his book, Gaia’s Garden – a Guide to Home Scale Permaculture.
It consists of:
Walnut – English or Black Walnut (Juglans spp.) – for nuts
Hackberry – food for wildlife
Wolfberry – food for wildlife and medicine
Peppers or tomatoes
Elaeagnus (Elaeagnus spp.)
Mulberry – for fruit or fodder
Currants – for fruit
Elderberry – for very edible flowers and fruit

I think that Toby Hemenway made a mistake recommending tomatoes in this guild, as tomatoes are very sensitive to juglone. Otherwise it is quite good, though it could be improved even more by adding more productive shrubs and an edible ground cover layer.
