About keying; Shall I have to roto these regions?
In the image below( which is a part of a 478-frame footage) I have marked two areas about which I’m a bit vague. In the Chroma-set there are many extra equipment and during some frames the main character even overlaps some parts which were never to get included in final keyed footage. Thus I think I have to mask the character and do some rotoscoping so that at final stage only the character is keyed and all other elements are suppressed out. Am I correct?(below is the footage’s one solo frame)

Yup — those areas need to be removed by hand. Which, when you consider how much you don’t need to roto, is a great deal.
Occasionally you can use a difference matte key to remove non-green background elements, but that works best when they are very different from the foreground (in your case, there’s a lot of dark colors in there — best to go with the roto).
