@sunnysunnet
1) It is managed from theme settings (at bottom). Clear browser cache and cookies when done
2) In oc-content/themes/tatiana/main.php you can modify these blocks
3) Sorry, not sure what you mean
4) In theme style sheets (oc-content/themes/tatiana/style.css)

3) Can you check my site from any android mobile? http://www.addever.com/ Then Just check the category block aliment. can possible to straight?

@sunnysunnet
Not sure why (maybe because you have 2 categories only), there are some problems with style sheet.
Open style.css
Find line:
.home #main-new .categories.c2 .col { float:left; width:302px; }

Replace it with:
.home #main-new .categories.c2 .col { float:left; width:48.5%; }

I try that code. But No Changes on Mobile View, After i change like this..
.home #main-new .categories .col { float:left; width:48.5%;margin-left:25px; }
.home #main-new .categories .col.c2 { float:right; }
.home #main-new .categories.c2 .col { float:left; width:302px; }
.home #main-new .categories.c2 .col.c2 { margin:0 0 0 25px; }
 Now Mobile view okay.. But Category icon still not changing. I clear catch and cookis but no changes..

Well, no idea what is your problem, can you explain how to get it?
