My female plant lost most of its leaves during the winter. Is this normal?
Yes, you appear to have a deciduous Holly. These will lose leaves and show the bright display of berries as you are seeing now. This is very healthy, and a wonderful sight.
It has black mold on a lot of the leaves. How do I get rid of it?
This is usually a secondary infection caused by insect damage. Usually aphids, but could be many species of insect. Can you include photos, so that I may give you the best diagnosis and correction method?
My holly bushes arer 10 years old This spring they have developed green like berries on end of stems.The berries are like blackberry texture.
I can't make a determination from your description. Has the Holly had berries previously? Distorted leaves and berries could be from pests or disease, so inspect the plant carefully and treat as necessary.

Leaves have a brownish color, how do I treat this.
Browning leaves indicate fungal infection or winter kill in most cases. Closely look at whether the browning starts with spots that enlarge and spread or the leaf overall turning brown in a uniform manner. If it is from winter kill, the leaves will fall and new ones emerge. https://www.gardeningknowhow.com/ornamental/shrubs/holly/leaf-scorching-in-holly.htm.

If you find spots, you are facing disease.
Why is my holly bush growing horizontal instead of vertical? It was growing vertical until a heavy snowfall a few years ago and now it is acting like a vine sending out long sideway branches! you can see by the picture the left side of the bush is now much lower than the right.
It does appear that the shrubs were weighted and began to grow in a horizontal manner.
The roots are always growing on evergreens and the weight of the snow shifted their position in the soil.
You can make some corrections with pruning, though I don't know if you can change the direction of the main branches with just pruning.
You may need to do a mini transplant to position the plants back into the soil.

There are lots of yellow leaves on our bush. The bush is about 10 to 15 years old. Not sure if this is normal?
Can you include a photo? If this is in a contained bed, then it could just need some fertilization. Are these newer leaves, or older leaves that are turning yellow?
