Garden update after moving

I brought five plants with me when we moved: basil, Romaine lettuce, green bell pepper, zucchini, and squash. The zucchini and squash seem to be slowly withering, while the others are thriving.

Anyone have any suggestions for the squash and zucchini? I took off the dead stuff yesterday and shook out the leaves, carefully. I also rinsed the leaves down on the top and backsides. I'm afraid they really might just need more space, but I can't plant them yet, unless our homebuilder would let me... The basil looks a little withered in the picture, but it just got water, so it was thirsty.
