That's not possible with vB5 without custom coding.

Adding number of posts in the Search module is not that hard. In fact, I have created on my site a custom Search module that adds the channel name where the post belongs. This is not displayed in the default view of the default Search module.

For the multiple entries per thread, that's a known "feature". You have to check "Started posts only" in order to only display one entry per thread but as expected, only the first post will be displayed and not the latest post in that thread.
