Loop Problem

Hello, I am new to worpdress, I have a problem about loop in frond end.

I have my own developed theme where I would like to show different records in three columns in the following way.

Basically three of the columns are same if I understand one then I can do with rest?

Note:- If you don’t have time to read to whole post just read one column and answer to that part, i am in trouble here. thanks

Column 1) In first column I have to show top (most recent) three blog-lines.

b)
list tag is not repeating in the loop as expected ?
