So Rahab was a Christian? Was she covered by the blood of Christ? Did she continue in her SIN once becoming a Christian thus making a mockery of the sacrifice?

Rahab lived several generations before Christ's advent. You can figure out the rest of your questions. But here's a hint: by some means known to Him, God applies the blood of Christ forward in time from the crucifixion and backward in time, also.
