Several of my Norwegian Spruce trees seem to be a lighter green compared to others. This spring, could I add any additives to green up trees?
A balanced or slightly nitrogen heavy fertilizer should help to green them back up for you.
The neighbors have a beautiful retaining wall that ends at the property line. I want to plant a Norway Spruce near the line to provide some privacy. How far could I plant the spruce without harming their wall with the roots as the tree grows?
Most trees like this can be planted about 5-10 feet from any structures to prevent possible damage from the root system. This article has additional suggestions for privacy plant screens: https://www.gardeningknowhow.com/special/spaces/plant-a-privacy-screen-plants-that-grow-fast-for-privacy.htm
My Norwegian pine tree houseplant has little flies. What can I put on it to stop the flies?
This is likely White Fly.
Neem Oil is good treatment and it is safe for people and pets.

Will the buried water line be interfered with the tree roots? how much space should be allowed?
Yes they will. You will have to contact your local utility services to see how far they require you to plant away from them. Each state will have different laws. Definitely check with the local laws before doing this.
we have a Norway spruce xmas tree in the garden which is going brown from the inside. we live in poole dorset and had all the heavy snow and ice not long ago. would this have caused this. we have had the tree two years and it was fine last year. could the adverse weather have caused this and can we save the tree.
Yes, extended periods of snow and moisture with cold, can cause this. It will likely recover on its own, and will not sustain any long term damage. This article will help: https://www.gardeningknowhow.com/ornamental/trees/spruce/norway-spruce-tree-info.htm
I live in central Massachusetts and have two 35 ft spruce trees that are growing into each other, planted 15 ft apart. On the southern side of these trees, is a 15 ft white pine that is growing into both. If I remove a 15 ft pine from in front of my spruce trees, will the brown areas of the spruce limbs come back to life and turn green again once they get the sun they need? Thanks!
The browning needles can be caused by several issues and needing more sunlight may not be the issue.
The most likely cause is winter burn but disease and pests can also be the cause.

We had a bad storm come thru on Aug. 2nd. Perfectly straight tree before the storm. It blew the tree side ways. 14 days later it shows no signs of dying. Should I just leave it alone, or try to some how straighten it? The dirt at the base of the tree shows no sign of movement. Thank you... Bruce
Either way is fine. It will grow happily in its new position, or if you would like, you can straighten it up. This article will help: https://www.gardeningknowhow.com/ornamental/trees/tgen/straighten-tree.htm
