Answer 1

You must read your contract of employment with care. Many companies insert an exclusion clause which bars you from working for a similar company or setting up your own in the same field. These clauses are binding and they can sue you if you fail to abide by them.

Answer 2

As long as you have not signed any work agreement, contract with a no compete clause in it.

Answer 3

you can.. but if your employer finds out, they may not be too happy about it, because it could create a conflict of interest and you can lose your job.
