My Lemon Cypress trees are getting brown. What is it? What can I do to save them and prevent the others from getting brown?
This is easily cured with Dolomitic lime, and Wettable sulfur. Apply both to the soil around the affected trees. This is a fungal issue, and wettable sulfur will take care of it.
it as much sun as I can. I wanna know, if its all dry, should i cut it so it grows again? Like is it dead or it might come back? I t does not seem like its getting better from week to week, its getting worse. Anything I can do to revive it?
No don't cut it back hard as long as it's still green, conifers do not usually respond well to heavy pruning.
Are you watering adequately? https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm
Is it too warm indoors. They prefer low 60s F.

There are too many male cones in Lemon Cypress trees like other cypress species. But why are there no female cones in Lemon Cypress trees? Why are there only male cones?
It can be difficult to pin down why one or the other sex cone appears more, but it is usually to an environmental trigger. This can be excessive heat or cold, improper humidity, or soil moisture, among many things.
This will usually resolve itself over time, though.

I bought a lemon cypress 3 weeks ago, on the first week, it was doing pretty well. But on it's second, I noticed it was turning brown. Now the top part's completely brown and the leaves are dry. Should I trim the top off? How do I revive this?
It sounds like it was overwatered, and is suffering from an infection. Once you start noticing large portions of the plant dyeing off, then it is not going to be worth salvaging. It will never recover its shape, nor will it look very pretty anytime soon. It is best to start over in this case.
The best thing will be to prevent this in the future.
This is done by ensuring that they plant's container has plenty of drainage holes to allow extra water out, and that the soil in the container is allowed to dry out thoroughly down to at least 2 inches, but don't let it dry out completely throughout the container. This will prevent future occurrences.

The plant was in a good condition for the first two weeks when it was brought home.
From the photo I don't see any browning of foliage, only what may be a little wilting of the foliar tips. So I would say at this point it is not dying.
This is most likely due to a water issue, too much or too little. How did you determine "moderately wet"? Did you use a finger or a moisture meter probe? Was that on the surface or throughout the soil in the pot.

Another reason for the disorder could be changes that occured with the move, or especially if it was transplanted.
I can't see from the photo if the plant is indoors or outdoors.If outdoors and you have had temps below 0 degrees F, it could be frost damage. Indoors it could be too warm.

My lemon cypress trees are stand alone. They are all leaning in different directions. So are the neighbors cypresses. My trees are all different ages; even the small ones are leaning.
There are quite a few reasons why these trees will lean. This can include wind, soft or wet soil, or shallow planting, or other factors.

My Lemon Cypress gets a little water sprinkling daily, lives in direct sunlight. It's color is a beautiful green but it is stiff to the touch. Is this normal?
Unfortunately, your photo did not come through. If it does not have some bend, or the scales fall off when touching or bending, then it is likely dead or partially dead.
If there is some life to it, and the scales do not fall off when you bend the branch, then it can likely recover.
It sounds like overwatering could have led to an infection which may have killed off, or is killing the tree. They shouldn't be stiff or brittle.
