offset individual of different categories in the same function

Hello everybody.

I have a doubt there is a function I want to do.

I have a page that has 5 box on the main page, and it does not last display of the latest post 4 above, the function that is wanted that last box that displays the latest updates of an offset for each individual box predecessor;

example:

Box 1 = category 10 (displays 4 posts)
Box 2 = category 7 (displays 10 posts)
Box 3 = category 20 (displays 6 posts)
Box 4. category 25 (displays 8 posts)

Box 5 = latest updates (displays all posts)

where would the Box 5 gives an offset for each individual category that exists on the page,

she would give an offset to the first 4 category 4, 10 for Grade 7 and so on.

Anyone have any idea how can I do this?

PS: sorry for my Bad english
