Frontpage different views

Hi all!
Right now at my blog I am using the_content(); to show all the entries on the front page.
I am wondering if it’s possible to show a group of posts in one way and then another in another way.

Example:
The first post shows full WITHOUT any cutoff at the <!–more–> tag.
The second to fourth post shows cutoff at the <!–more–> tag.
The fifth to eighth post shows only the title as a link.

Is this possible to modify the output and limit the number of posts in a special view?

Thanks to everyone who spends some time trying to help…
