No secret vendor in floor 5 anguish sot?

I am in its position and i couldnt find it?

Does it have several spawn locations?

He has a chance to spawn. Same with the one in Bastion of Chaos last floor.

I don’t know if they just changed his location or if he really has multiple spawn locations now, but instead of his (for me) usual position in the south-east last time I visited SoT he sat somewhere in the north-west.

The vendor has always had three different locations in my experience. I’ve never had him not show up, so I suggest just keep exploring.
