Add category and two column

Hello,
I have some questions, thanks for replying:

1) How can I make it appear lacation in this view of ads? https://wpadverts.com/wp-content/uploads/2015/04/adverts-list.png

Like under the date put “New York”

2) How can I put also after keywords and location, add another field of filter who is category?

3) When you open one ads, you can see “By author xxxx”. Can be indeed “by “contact person” ?

thanks
