I have white spots that can be rubbed off with a fingernail on my indoor Kentia palm. Any ideas?
It is palm scale. These articles should help:

I have three palm trees which sustained damage because of an extemely cold winter in the South. The Kentia palm stalk is green at the bottom, but the fronds are brown (but not stiff). Do I need to prune or cut back to help with growth, and if so, how? Also, I have A Majestic palm and Pigmy palm in similar situations. Do I prune or cut these as well, and if so, how far down?
Remove any yellow or brown fronds this spring but do not remove any of the green. These articles will help you as well: https://www.gardeningknowhow.com/plant-problems/environmental/how-to-tell-if-a-plant-is-dead-and-how-to-recover-an-almost-dead-plant.htm

Can a Kentia palm live outdoors in southern California with shady, indirect sun?
These trees are hardy to 25F, so as long as it does not get colder than that where you live, it can grow outdoors year round. It can tolerate partial shade, so as long as the indirect light was pretty constant through the day, that should be the equivalent of partial shade and the tree will be fine.
I have a Kentia palm that is sick and appears to be dying. It is planted close to another Kentia, which is thriving, and both are treated the same. The one in question was by far the largest, but now it is not. Any suggestions?
I would consider two possibilities. The first is that the larger palm has pests that are hurting the tree. Check the plant closely. Scale is a common pest forpalms, but it could be something else. I would even say go ahead and treat the palm with neem oil as it will not hurt and will kill any pests that you may have missed.
The other is that the tree may be dying from old age. Do you know how old it is? Trees, like all living things, have a lifespan and it may be that this one has reached its end.
I have overfed my Kentia palms. The older leaves are burning very fast and I have cut a good number of them already. I added the palm fertilizer in the soil when I was planting them. Should I take them out and clean them? Or is there another solution to that? Those palms cost me $200 and I really would hate to lose them.
One of the best ways to remedy this is to simply flush the plant soil with water 2-3 times, allowing it to drain before each time.
This palm is less than a year old. We had one in the same spot, which was 30 years old or more. We chopped it down because the fronds were not growing.
This is normally an indicator that the plant is not getting enough humidity. Try raising the humidity in the area some by spraying down the leaves in the morning a few times a week.
We purchased a Howea Fosteriana Kentia Palm from Ikea, and since re-potting it, some leaves have gone brown and others are going wrinkly and dry. It is situated in our hallway, not in direct sunlight, but the hall is bright. When I potted it, I used fish bone meal as a feed for it. Please help.
It may be suffering from transplant shock. Increase water and also give it a little sugar water. In a few days, give it fertilizer at half strength.
