    Why are you using ISOs? you should be downloading the installer from the App Store.

    This is your problem. 10.5.5 is Leopard, not Snow Leopard. You'll need to buy 10.6 Snow Leopard from Apple before you can upgrade beyond there.

    Mac OS X 10.5.5 is Leopard. You cannot upgrade to 10.8 or 10.9 from it, only 10.6.8+. You must first purchase a Snow Leopard 10.6 disc from Apple for about $20, then upgrade to 10.9.

    Right. Install 10.6, then run Software Update until it's fully updated, then you'll see the App Store app in the Applications folder. Mac apps don't come from iTunes and the operating systems aren't distributed as an ISO.

    You can't install either of those from Snow Leopard, unless Snow Leopard is fully updated to 10.6.8.
    You also need to have 2 GB or more of RAM installed.

    Mountain Lion, or Mavericks installers do not come as an ISO - they are applications.
    Even better, you can make a bootable installer from that installer application, and copy it to a USB flash drive (8 GB is ideal). That will allow you to use it as a stand-alone installer, and you won't have to wait for the install files to download.
    It's a simple task, and there's good utilities that do the job for you, such as DiskmakerX. http://diskmakerx.com
