I have a red camellia and it's infested with something. Whatever it is, it's all over the back of the leaves. Now what is it and how do I treat it??? I thought about cutting it down a lot, cause like I said, it's covered with whatever it's called. Please help, Thanks.
It sounds like you have either aphids, mealybugs or scale. These pests commonly appear on the back of the leaves.
They are all treated the same way. Treat the plant with a pesticide. I personally like to use neem oil. This article has more on neem oil:

Based on what I read at this site, it appears that our white camellia bush has bud drop. The buds never open. They stay hard as a rock, then they turn brown. Only one or two actually open to a bloom, but they too have brown leaves. The location gets a lot of rain coming off the roof. I am not sure if it can be dug up at this point because it has been there for years. Any suggestions on what we can do to save the bush?
It actually sounds like you may have a nutrient problem. Have the soil tested and in the mean time, use a fertilizer with a slightly higher amount of phosphorus in it. They are normally sold as "bloom booster" fertilizers. Just make sure that the fertilizer is providing all 3 kinds of macro-nutrients, nitrogen, phosphorus and potassium.
I have two camellia bushes that are at least 4 years old, but one seems to be dying. I first noticed it right after temperatures in Georgia dropped into the teens and single digits. They are not located side by side, but approximately 15 feet apart. One camellia is blooming profusely and looks great, but the other looks really bad, with lots of dead foliage. I think they are the same variety (pink blooms). Do you think the cold weather may have done this damage?
It is possible. In a yard, micro-climates can inadvertently be created. It sounds like your thriving camellia may have been in one of those. Micro-climates are a small place where the temps can stay warmer or colder than the rest of the yard. Things like nearby buildings and trees can influence this.
Is it possible to have aphids on my camellias? I was notified by a salesman selling lawn maintenance that my camellias were infested with aphids, due to the shiny substance on the back of the leaves.
Yes, it is possible. It could be aphids or scale. Both cause that on plants. Here is more information on both: https://www.gardeningknowhow.com/plant-problems/pests/homemade-aphid-control-a-natural-way-to-kill-aphids.htm

My camellia plant has black soot on some of its leaves. Can you advise me on what the solution is?
It is sooty mold. This article will help you with that:

There is black soot like matter covering leaves of camellia tree.
It has sooty mold, which is a symptom of a pest infestation, usually aphids. Treat the plant with neem oil. This will help with the pests and the sooty mold. Here is more information:

I have a thriving 3-4 foot camellia that looks incredibly healthy, dark green shiny leaves and no apparent disease. I re-potted it about two years ago, fed it, etc. It has grown approximately 18 inches but has not produced a single bud. Any tips?
I would add phosphorus to the soil. A lack of phosphorus will cause a lack of blooms.
