  1. Question

    Do we have a chance that Opportunity has found fossils of complex organisms? There are the three rocks that may suggest this.

    No one has found any fossils in any of the photos returned from the two MER rovers on Mars, Spirit and Opportunity. The website you suggested for seeing fossils seems to me to have little science; it is mostly unsupported speculation. I recommend instead that you look at the NASA websites such as [http://marsrover.nasa.gov/home/index.html]. If anyone ever does find a fossil on Mars, I am sure it will be widely publicized.
