Why is my orchid's stem turning yellow?
If the stem previously had flowers on it, it's normal for it to turn yellow after the flowers fade. You can remove the old flower spike as described here:

My Vanda has aerial roots growing from the main part of the plant 1/3 and half way up the plant. I see no signs of a flower stem. The last time my Vanda was in bloom was this time (November) last year. I spray the root system, which is over 3+ feet long, with water that has a trace of orchid fertilizer in it. I also have two Keikis growing at the base of the plant. What am I doing wrong?
It appears that these can be quite picky, requiring ver certain temperatures, and humidity conditions. This article will help you to figure out what is missing: https://www.gardeningknowhow.com/ornamental/flowers/orchids/vanda-orchid-care.htm
Should I clip off the dead bloom?
Yes, you can clip off the dead bloom and any remaining stem that the bloom was on, but don't cut into the leaves.
The plant is extremely healthy. It's just gotten over a blooming episode I have got the stock back and now I am noticing these little black tips on the end of my roots. My roots are grey and green which are very healthy none of them are mushy or anything. What are the black tips?
This is usually an indication that the water being used is what is called "hard". This means that it is very alkaline, and most likely contains high amounts of calcitic lime.
If you are using tap water, I would recommend using purified, or RO water. This will stop the problem from happening in the future.

Do I need to snip off the black tips? Or are they harmful to the plant? The plant has been extremely healthy and has been flowering quite often and the roots are not mushy and grey white in color and green Only When Wet.
Do I need to clip off the black tips on my Vanda roots or are they not going to harm the flowering of the plant? That plant has been extremely healthy and flowering
I saw a video that said I can cut the top off the stalk of my Vanda, as long as I left about 5 rows of leaves below. I took the top 1/4 off the plant. It is not happy and is now giving me yellow leaves on the bottom and top. Did I just kill this plant?
It will recover, there is no need to worry. Pruning them won't kill them, but I would suggest doing this in spring, and not this late. It will probably suffer for just a bit before recovering just fine. A picture can help me to see the damage, though.

Hi my name is Patrick and I have collection of 10 vandas all grown in my bathroom with t 5 h.o. Light and humidifier. Almost all have bloomed two are to young. I bought this vanda Coerulea Alba August of last year and it was in bad shape at the roots and crown. The crown top of the plant lost its leaves either from crown rot or they cut the top ? I don’t know and don’t know what are the little pyramid things growing out of the top. I thought they were going to bloom but they haven’t done anything. What is happening at the top? And what can be done to get it to grow and flower? Can the plant be divided? Thank you for your time
It is hard to say what happened to the top. I can say that those are aerial roots that are protruding from the top. It will become another rooting portion of the plant.
As for why it won't flower- This could be due to age. It may not be old enough to set blooms yet. Proper care will tell over time. Alternatively, you can fertilize with an orchid fertilizer as a foliar spray. This can help give it a boost to start the flowering process.
