I have a 'China Girl' and 'China Boy' holly berry bush and I was wondering if I am able to plant them 30 ft. apart and still produce berries?
Yes, they can be planted up to several hundred feet apart and still cross fertilize.
I was up north and saw some China girl holly, hosta plants, and blue juniper. I would like to take some back to southwest Florida to plant. Will they grow there or not?
Yes, you can grow both hosta and holly plants in Florida but just be sure to provide them with their proper growing requirements--especially some shade.
I purchased a China Girl Holly and now need the China Boy Holly. Or do I? Some varieties of holly do not need the partner. Please advise.
Yes, it is recommended that you have both male and female hollies in order to produce berries. The following article should be of some help to you:
I have one holly berry (China girl, my sister calls it) and many non-berry bearing (China boy?) bushes around my acre yard. I think I've figured out how to get the China girl to bloom almost every year, but the China boys are so gangly and unattractive. When should I trim them and to what degree?
You should not cut away more than 1/3 in any one year. Also, any pruning should be done in winter, though doing so now is ok. This article will help: https://www.gardeningknowhow.com/ornamental/shrubs/holly/trimming-holly-bushes-how-to-prune-holly-bushes.htm

China girl holly, dying in sections--one stem dry, brittle and still has berries but they are drying up. No break in branch and there are no animals around to damage. There are others planted next to this one and they are doing well. Also, there is no sign of insects.
There are several things that can cause this. One is that it is not getting enough water, either due to under watering or due to a root rot or other damage to the roots.
Where it is planted may also be affecting it. While the other plants are fine, it may be in a spot that gets more wind or more sun, which can also damage it.
And it may also be a fungus. There are several that can cause branches to die off.
I would check the roots for damage and treat with a fungicide. This may help.
What is going on with my Holly bush? Small green berries form, but never mature to red and now most of the berries are brown and shriveled. Spider webs with small spiders are forming all over the new bushes. What to do?
There is a pest called a holly berry midge. It gets into the berries of hollies and they will not turn color when they are infested with them. I suspect that this may be your problem. This article will help:
Treating the shrub with neem oil should help with the spiders.
