Answers:
What do you have blocking it up??
Can't be much or legal!

No footings?
Concrete blocks?

Need more than one jack so you don't do any damage to windows and doors and a couple friends to help you bring it to level at the same time!

Cheapest way without high dollar equipment is to use a water level and set up the blocks all to about the same level and have some shims there to fine adjust your columns
