My potted herbs (Chives, Mint, Thyme, and Parsley) are sprouting mushrooms. They are not the yellow mushrooms that I keep reading about, but rather small brown mushrooms, which die usually the same day as sprouting, but no longer than the next day. I've read the how-tos of getting rid (or trying to) of them, but I'm curious about whether or not they are damaging to my herbs. What do you think?
They are not damaging to the plants. It is a sign that they soil is organic rich and that the plants are getting enough water but not too much. They may be lacking in light though, so if the herbs look leggy, I would move them somewhere brighter.
Can I plant herbs in an outdoor container with other flowers? For example, can I plant rosemary, basil, or cilantro in the same large outdoor pot with petunias, marigolds, etc?
Yes, as long as they have similar water needs. For example, basil and petunias would be good, but I would not plant rosemary with petunias, because rosemary likes less water while petunias like more. Rosemary and marigolds or geraniums would be good, because those flowers can tolerate less water.
I have to do my gardening inside and need to know the size and depth of containers for as many herbs as you are willing to give me. Room is not a problem. I have containers of just about all sizes [except strawberry jars and half barrels]. I can get those if you think they are needed for a certain herb.
As long as there is adequate room for root growth and good drainage, most herbs do not require anything real deep—at least 4-6 inches should suffice. This article will help with growing herbs in containers: https://www.gardeningknowhow.com/edible/herbs/hgen/growing-herbs-in-containers.htm
I have a variety of herbs planted in self-watering planters. Most of them were plants that looked quite healthy when I purchased them. They are in different pots, but they all have light brown spots, or most of the leaf is brown. What can be the cause, and what can I do about it?
It sounds like they have a fungus. Treat the plants with a fungicide and this should help clear it up.
I have a metal trough-shaped, verdigris-colored container that I bought at Marshall's a few years ago. Printed on the bottom is: For decorative use only. Not for food. Can I safely plant herbs in this?
When growing herbs indoors in a container, the most important thing to remember is to provide a growing environment of nutrient rich soil that has good drainage yet holds moisture. I would recommend placing a plastic liner inside before adding plants or even choose a small plastic pot that will fit inside the metal container.

Just planted vegetable and herb seeds in small pots one week ago. Now I have a white mold on top of the soil of the planters. What should I do?

I have a few indoor plants, mostly herbs. They are sitting on a window shelf I made so that they can get the sun that they require. I noticed this morning around the rim of the pot, which is your basic orange ceramic pot, a ring of something white, kind of chalky. Does anyone have any idea what this could be?
It is likely residue from your water. Minerals and chemicals in your water are left behind when the water evaporates, which can look like a chalky or powdery residue. It normally isn't a problem unless you have a water softener, which means that you will have water that is higher in salt and that salt will be building up in the soil of the plant, which will eventually harm it.
If you do have a water softer, I would recommend switching to filtered or bottled water or rain water for watering your houseplants.
