(1)If a particular dmoz editor is unlikely to approve you and you change the category which you applied for, will it be sent for review to a different editor?

No. The application reviewers don't specialize by category. But every time you apply, some "meta-editor" has to choose to review the application. It is likely to be a different person each time anyway.

(2)If a category has more than two editor what are the chances of getting selected for that category.

The number of editors already in a category is the smallest factor in the decision. If you can show that you can contribute to a category, what would it matter how many people are contributing already (or have contributed already)?

(3)Do they use auto responder for review?

No. Each application is reviewed by a human. But there is a boiler-plate rejection letter listing the most common obvious problems. The meta-editor chooses whether to send it, and whether to add comments to it.
