How long will it take this fake planet to rotate and revolve around its red giant sun?

It appears there are a couple of things you don't understand, please read on. the red giant phase for any star is a temporary condition. The sun for example will become a red giant in about four billion years. That will only last a few million years. Then it will shrink to a white dwarf. In terms of stellar evolution, a very short time. If a star is a giant because of large mass, it will probably never make it to red giant phase, it will probably super nova long before that can happen. Like supper nova 1987A. That is a very short lived star. You need to get some more information before you commence speculation on this hypothetical planet.
