Dear Saravana,
ETH Zurich (Swiss Federal Institute of Technology) is Switzerland's top-ranked university and is highly competitive. Other well-known names include University of Zurich, University of Geneva, Ecole Polytechnique Fdrale de Lausanne (EPFL), University of Bern, University of Lausanne, University of Basel and University of St Gallen (HSG).

From which university have you completed your B.Tech?

To pursue MS from abroad, you have to appear for TOFEL and GRE exam.

GRE is not required if not mentioned by the university. It is mainly required in US. If you have good academic performance, you need not take GRE even if you are applying to a top university in Australia.

I don't think exams like GRE, etc. is required unless the university really requires one. Applicants with outstanding academic track record are taken. International applicants must provide IELTS or TOEFL scores, German language knowledge is also preferred. Always check with the universities prior to applying.

MS or M.Arch is for design course.
