Dear Naresh!
ad 1) Hopefully a lot of observations (for 6 linear regressors >18).
ad 2) Fine. That's called multiple regression.
ad 4) From your last sentence I guess you think that (some) assumptions of parametric regression do no hold. Have you tried the more common approaches: transformations or weighting? If this doesn't help, you may opt for robust regression. You may try to minimize not the sum of squared residuals (like in OLS), but the sum of absolute residuals, or the median of residuals, or...
I don't see a need for Monte Carlo here.
