My 3 rosemary plants (2' tall. . . about 5 yrs old) have suffered until last fall from the shade of an unhealthy dogwood tree, which has now been removed. They've struggled for sun but are spindly and formless despite their newly improved state of health now that they have full morning sun.

I bought a beautiful Rosemary plant last fall and its tag stated that the plant could withstand temp. s of 0 degrees. Now it has lost most of its leaves, appears they dried out and fell off. The tops are sprouting new leaves, what should I do?
Give it some water and care as usual. If there is still some dead or dying growth, you can cut that out. These articles should help: https://www.gardeningknowhow.com/edible/herbs/rosemary/growing-rosemary-plants-rosemary-plant-care.htm

Could you tell me what are the small, white, wet, squishy beads that are on my rosemary plant?
Is it foamy? If so, it could be spittle bugs. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/insects/spittlebug-control.htm

Rosemary, being a perennial, can it be planted in the colder regions?
Rosemary is really a zone 6 plant. You can get it to winter over in zone 5 if it is in a sheltered location, like near the foundation of a house. Even then it will be iffy. It is best to either bring it in for the winter or buy new ones each year.
I have made some liquid plant feed from comfrey leaves and water. Is this suitable for rosemary? (I know it is good for tomatoes)
I would not use fertilizer on rosemary (or most herbs). The reason being is that fertilizer will cause rapid growth and the plant cannot keep up with producing the chemicals that create the flavor at the same rate as the growth. It results in a less flavorful leaf on the plant which means a poorer quality herb for cooking. However, this does not mean you cannot do so. It is entirely up to you and if you're not using the rosemary for cooking, then it really shouldn't matter anyway. If you decide to fertilize, the mix your made should be fine.
I have Rosemary, Thyme, Basil, and Parsley growing indoors. I am noticing small fruit flies all living in the dirt. What are they and what can be done?
It sounds like you have fungus gnats. This article will help: https://www.gardeningknowhow.com/special/children/fungus-gnats.htm
Neem oil will help take care of these pests but will not hurt the plants. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
