Only the 3rd shot shows for me - the spider looks like a Meta Segmentata (lesser garden spider). The angle you have chosen to shoot from shows how the spider hangs from a flat orb web and you have even managed to capture it eating something (a little black fly at a guess!). The subject is also well isolated form the out of focus background
A tripod and a still day would be preferable to using ISO 800 though. Just the slightest of breezes makes shots like that very difficult....I think I can let you off with the focus being a little too far back to get the abdomen sharp this time
Even although I can't see the first 2 images the EXIF would certainly suggest you are going in the right direction - manual focus and small apertures. It definately looks like learning to me
