HP Procurve 1810G-8

Create 7 VLANs, assign each port from 2-8 as untagged each in a different VLAN, trunk all 7 VLANs to the router out port 1.
On the router configure access lists to prevent traffic between the ports as required.

Just to summarize. I should create 7 VLANs on ports from 2 to port 8. When i set VLAN for port 2 it should be untaged, and rest of the ports excluded?
Next i made the same with the rest of the ports (from 3 to 8). What with vlan for port 1? How should it be set? (untaged and rest of ports excluded)?
After that trunk should be set and all VLAN should be membership with port 1? What about port 8? I would like to have access on all ports from it as from port 1.
Why you wrote that i should configure access list on router to prevent traffice beetwen ports? I want that switch will be able to prevent traffic beetwen ports throught VLAN.

Port 1 has all the VLANs tagged.

Port 8 is the same as the other ports.

The switch can't do that - you have to do it on the router.
