display multi related post separately

Hi, I need to display multi related post separately. I put related_posts() in a shortcode and I use that shortcode where I want. But I have 2 problem: first, everywhere I use shortcode, related post shows up after first related post display, second, I need display different related post, but both result, display one related post. How can I customize it?

here mycode, my expect, result:
[related_post] related_post1 related_post1
blah blah blah blah blah blah related_post1
[related_post] related_post2 blah blah blah
