Normally there are no red blood cells in cerebrospinal fluid, but some kinds of injuries can cause bleeding into the cerebrospinal fluid in which case there will be red blood cells.
Cerebrospinal fluid is formed from blood by the choroid. This is usually produced through the process of filtration of blood in the brain.
