Moving ( relocating) Ads within sidebar

Hi:

I have a few ads of various sizes; typical is 125×125. All Ads are apparently coded to be placed very close to the right margin of the post content area. Every time I add another banner, it is placed below the previous one. I have about 380 px unused space in the sidebar and I would like to reset various ads so they will be spaced, horizontally, from each other, for example, with a space between them of about 10 pixels.

Is there a code that I can insert that will move these ads to the right with x px’s between them? I would like to have two to three across extending to within a few pixels of the right hand margin of the side bar. Where would I need to modify the code?

Thanks.
