Urine contains several different molecules (and is mostly made up of water), however, diregarding water urine mostly contains urea.
Yes, protein can be found in the blood of the glomerulus, but normally it should not pass through the filtration barrier into the urine. The glomerulus filters blood, allowing water, electrolytes, and small molecules to pass while retaining larger molecules like proteins in the bloodstream. If proteins are detected in urine, it may indicate a problem with kidney function, such as glomerular damage.
The two main substances found in urine are water and waste products, such as urea, creatinine, and uric acid.
If you are talking about three substances that are normally found in blood but not in urine, they are leukocytes, erythrocytes and glucose.
Blood proteins and blood cells are indeed too large to pass through the filtration membrane in the kidneys. During the process of filtration in the kidneys, small molecules like water, electrolytes, and waste products are filtered into the urine, while larger molecules like blood proteins and cells remain in the blood. So, they should not normally be found in the filtrate that is eventually excreted as urine.

Sometimes. There are certain molecules in the brain that DO NOT cross the blood brain barrier, and so they don't easily leave the brain. These would not appear in the blood or urine to any appreciable extent. However, there are many others that do LEAVE the brain and are found in the cerebral spinal fluid, the blood, and yes, even in the urine. It is not an easy task to measure urine and then figure out what is going on in the brain, however.

Protein isn't normally found in urine, because so many people these days are on Methamphetamine, a very strong drug used by individuals seeking an easy escape. If this drug is abused, the protein from the mitochondria in your cells don't diffuse through the cells into the stream of urine. -Jericho
The most logical answer would be urine, and it is!
Yes, sulfates, phosphates, and chlorides are found in urine. These compounds are waste products that are excreted from the body through the urine. Their presence in urine can indicate various metabolic processes happening in the body.
creatinine
No
Protein nor sugar should not be found in the urine of a healthy person.
Glucose is found in the urine from time to time.
