Other vegetables in the same garden did fine - tomatoes, peppers, peas. Squash looked great for a while, several small squash were developing, then the vines got yellow and droopy, and the squash stopped growing.
Your squash plants may be suffering from the onset of bacterial wilt, which will kill the plants and there is nothing to do but pull them up. Here is more information on the problem: https://www.gardeningknowhow.com/edible/vegetables/squash/signs-and-treatments-of-squash-wilt.htm
I planted a large bed this summer with decorative annuals in the spring. Within a few weeks a plant began to grow in the bed that was not what I planted. Curious, I let it grow. It grew quickly and developed very large (12 inch or more in diameter) leaves and stalks that were 1. 5 inches or so in diameter. The leaves and stalks had hairs on them. Finally, a bright yellow flower developed and web searches lead me to believe it was a pumpkin plant as the flower was about 5 inches in diameter and had 5 distinctive pointy petals. Now I have fruit. It resembles a delicata squash; however, a neighbor thought it could be a gourd. How can I most easily determine if it is a squash or a gourd?
Gourds and squash are actually in the same family so it is likely that you have a gourd plant. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/gourd/growing-gourd-plants.htm
Squash will not grow/make in my raised bed garden. I have plenty of composted manure in it. I do not understand this, as everything else makes plenty. What can I do? Thanks very much.
try soaking seed in potassium nitrate it mimics the digestive system of animals and nics at the outer thin layer membrane of the seed.dont have PN try this superthrive soak for 2 hours then plant only a quarter inch no deeper. GOOD LUCK this works for me every time
I am not concerned about cross pollination but about squash bugs and diseases. I have read that you should not plant cukes near squash because of spread of disease. (Rodale's Organic Gardening book) How far apart is ok?

I am a first time gardener and trying really hard. I have noticed that my squash and zucchini have roots that look like they have been hollowed out. It feels mushy and have a foam like look. Although they are blooming and they look healthy, is it safe to leave them or should I pull them?
One of the most common squash problems: Squash vine borers. These fat, white, 1" long larvae burrow into the stems and exude masses of yellow-green, sawdustlike excrement. Slit stems lengthwise above injury with a sharp knife and kill larvae. Cover cut stems with moist soil so they will form new roots. Injecting stems with BTK or parasitic nematodes may also control borers. To reduce problems, plant the cultivar which is resistant to vine borers. Or spray base of stems with BTK once a week in late spring and early summer.

I had made the mistake of putting down 2 different pesticides within a few days of each other, and now what were once hearty healthy zucchini, squash and pumpkin plants are now wilting and dying. Due to such recent heavy rains I had hoped that the pesticide would wash off or the plants would get enough water so that they wouldn't wilt but it is not working. What do I do now? And can the plants be saved?
I think the key phrase is ''recent, heavy rains''. Squash and pumpkins need adequate moisture, but they don't like to be waterlogged. They are susceptible to fungus in hot humid weather. This article explains: https://www.gardeningknowhow.com/edible/vegetables/squash/tips-for-growing-squash.htm
I would like to know if you can grow squash, like yellow squash and zucchini,
as hydroponic?
Yes, it is possible. Nearly any plant can be grown hydroponically. The issue is that squash plants get very large, even bush varieties and it can be quite difficult for the home hydroponic gardener to accommodate their size and support their size on typically elevated hydrponic beds.
If you are going to try growing these, I would recommend that you grow vining varieties as these can be coaxed up strings or wires and would make it easier to accommodate their size.
That being said, here is an interesting video from a gentleman who is growing bush varieties hydroponically:
