I planted squash and cucumber plants in a raised garden bed. I use a hose pipe to water and they have grown very well. But now the lower levels of the leaves are turning yellow and look like they are going to die or just fall off. This is also happening to several of my tomato plants. The upper portion of the cukes and squash are looking very green and healthy. Am I watering too much or not enough?
These yellow leaves can be caused by both over and under watering. The garden really only needs about 2" of water a week. I would recommend putting in a rain gauge to check how much water is falling on the soil and adjust watering after that.
I have many flowers with small cucumbers. But when the female flower dries up, the little cucumber shrivels and falls off also. Why, and what can I do about it? I do not have a single growing cucumber on the vines, but plenty of male and female flowers.
This is typically caused by a pollination issue. These articles will help:

I was wondering how to properly place cucumber seedlings in a Topsy Turvy planter? I have 8 seedlings and I am not sure. Do I place them all together?
You would plant them like you would tomato plants, so only one (maybe 2) seedlings per planter.
I planted Burpee bush cucumbers last year and I got some delicious cucumbers but many of them would bloom and start growing straight, but then the blossom end would not continue to develop and would just curl up, while the portion by the vine would develop normally. What could be causing this to happen to the fruit?

I've planted a small vegetable garden - tomatoes, cucumbers, zucchini, etc. Now I have a lot of flowers on tomatoes and cucumbers, but this year there are no bees or other insects to do pollination (previous years they were plenty). What should I do in this situation? Will any cucumbers grow without insects?
You need to encourage more pollinators into your garden and, if that is not possible, you may want to hand pollinate the flowers. Cucumbers can be pollinated the same as tomatoes. These articles will help you: https://www.gardeningknowhow.com/edible/vegetables/tomato/pollinate-tomatoes.htm

Today I saw that my cucumber plant leaves are all wilted. My plants are in large containers. It recently rained for five days down here in Georgia. I have tomatoes and sweet potatoes in containers also. Their leaves look fine. What has happened to my cucumbers?

Some of my leaves on all of my plants in my garden are yellow. On my cucumber plants it is more of the tips all around the leaves. On my tomato plants it is more around the bottom of the plant the leaves are a little yellow. And the same thing with my pepper plants. HELP
This is an indicator that the plants are underwatered. You should increase water to the plants and this should help.
It is also possible that they have received too much water, but this would only happen if they were growing in soil so saturated that it is basically standing water. Some areas have received large amounts of rain, so this could be a possibility. If it was too much water, the symptoms will fade once normal rainfall returns.
