3 query loops in 1 page

hey!
I want to have this in my new site:
1) loop of 3 latest posts
2) loop of 5 lateast posts
3) loop of all posts

1,2 are in the sidebar.

I tried to do this with

<?php query_posts('showposts=3'); ?>
<?php if(have_posts()) : ?>
<?php while(have_posts()) : the_post(); ?>

--stuff--

<?php endwhile; ?>
<?php else : ?>
<?php endif; ?>

I copied & pasted that code couple times and changed the showposts=3 part but it messed the whole blog…

anyone has any solution? thanks!
