Thanks from me too; this saves me the hassle of having lots of small stories. I'd like to help if I can ever get some free time from reading stories!
Most of these stories I haven't read before, but of the three I recognise:
He Walked Around the Horses: sometimes considered to be a Paratime story (although it's not explicitly one, it could be interpreted as such)
Graveyard of Dreams: As DMcCunney mentions, it's a short version (very different ending though, I recommend reading both versions) of 'Cosmic Computer' so is a Terro-Human story
