Your SSD PCIE is not showing many small partitions, and disk 0 to 3 are NOT your SSD and HDD. According to your disk listing, disk0 and disk1 are your physical disks inside the computer. I would assume you have two SSD installed in the computer. Nothing in that list shows you have anything connected to your computer large enough in capacity to be a modern HDD (unless it has a corrupted header/partition table).
Disk2 is likely a bootable install device, maybe a USB stick or SD card. Disk3 is the logical install image likely opened off disk2. Disk4 is also a logical image (part of the install system) likely opened off disk2. Disk5 thru 16 are system generated logical mount points that show up anytime you boot into an installation and (like I said already) can't be deleted. Once you boot into a standard install version of OS x those won't be there. Unless I'm misunderstanding what you are asking, there is nothing to be deleted according to your disk listing.
If you are trying to install windows, your best bet is to use boot camp to prep your system. There are workarounds to prepping your system manually (I've done it before) to install windows but those are often tedious and not always certain in outcome.
