Default Need help with 3 spiders

Here are 3 spiders I photographed a few years back and haven't been able to ID, so I'm hoping someone here will recognize them.

The first one is possibly a Dolomedes of some kind but I'm not sure. It was photographed in oak woods and was small, body length of maybe 7mm, so I think it may have been a young one.

The next two were web-weavers found in grass of an old hayfield, not the best photos, as I didn't bring my tripod that day, but you can see the markings fairly well.

A ID I've been considering for the first one of the second two is Larinia directa, but it doesn't seem to quite fit, as I think my spider is shorter and stubbier than it should be for L. directa.

Any help with ID's would be welcome.

Thanks,
John

The first spider could be an immature Dolomedes tenebrosus - see small spider - Dolomedes tenebrosus - BugGuide.Net for an example; the second one could be a Larinia - see tan spider - Larinia directa - BugGuide.Net for a stockier example; the third is a long-jawed orb weaver (family Tetragnathidae); likely in the genus Tetragnatha - see Tetragnatha elongata? photo - Tom Murray photos at pbase.com for an example.

Thanks Suunto, that helps. I had been looking at the Tetragnatha genus for the third one but wasn't sure. I've seen and photographed a huge Dolomedes tenebrosus before, didn't see the similarities to the first shot, but that may indeed be it.

Thanks,
John
