Pine tree is losing its needles and leaving bare stems starting at the top. Also, my quaking and a few other trees have cuts or holes going into the trunk and some limbs. What can be causing these problems?

My pine tree became suddenly orange all over in a 2-day period. One day it was green and the next orange everywhere. I have only lived here for a year, but I can tell the tree is at least 30 years old. I have 2 other trees near it and am worried about a disease that could affect them all. I am familiar with pine beetles but am not seeing any signs of such bugs. What else could cause this to happen so quickly?
This article explains it a whole lot better than I could: http://web.extension.illinois.edu/state/newsdetail.cfm?NewsID=26364
My pine wood deck on my balcony (in a high rise building) keeps oozing sap. I want to cover it with synthetic grass. Do you see any problem with that? I figure the sap will help glue the grass down. :)
This question would be best answered by a vendor of the product you are planning to install.
When growing pine tree seedlings indoors, how much light do they need? How much water? Also, what temperature and what kind of soil do they require?

Can I grow pine trees from pine cones and, if so, how do I do it?

My friend has a very young pine. It's not doing so well and hasn't been for awhile. I'm not sure what type o pine it is. At first it was turning yellow from over watering and I advised her to ease up a little. That was a couple of months ago. Now it's turning brown. Is this normal? It's also in a 20 gallon planter outside. Is this a sign that we need to transplant? I don't know much about pines, especially younge ones. Any advice would help. Would hate to see the little guy die.
If it is turning brown, it is dying. Likely the overwatering caused root rot to set in.

We want to know if we need to pull out the floating seeds right away when we soak them, or wait for 24/36 hours and then pull out the floaters. We currently have Afghan and Aleppo Pine seeds and have already started to plant; however, it does not make any sense to us that we should wait until the soaking process is over to pull out the floaters, seems like the bad ones would simply absorb water and sink anyway.
Yes, the floaters are typically removed, as they are usually not any good. The viable seed generally sink to the bottom. Most of the time seeds are left to soak anywhere from 12-24 hours. This article will help explain: https://www.gardeningknowhow.com/garden-how-to/seeds/soaking-seeds.htm
