What are all the layoutparams in “BlogPostList” Macro apart from displayTitle, displayCalender. As I need to post only content part of the Blog on other page .
I don’t know these macros but from what I understand from http://extensions.xwiki.org/xwiki/bin/view/Extension/Blog%20Application#HBlogPostListMacro the layout params depends on the layout macro used.
You could check the sources at application-blog/application-blog-ui/src/main/resources/Blog at master · xwiki-contrib/application-blog · GitHub
For example for the “full” layout: application-blog/application-blog-ui/src/main/resources/Blog/BlogPostLayoutFull.xml at master · xwiki-contrib/application-blog · GitHub
Once you’ve figured them out, it would be great if you could edit the documentation page to add them, on http://extensions.xwiki.org/xwiki/bin/view/Extension/Blog%20Application#HBlogPostListMacro 
Thanks
