Squid should run just fine in a HA LVS setup. See the LVS documentation
for how to set up LVS as none of this matters to Squid. Provided the LVS
setup is correct Squid will be happy.

Yes. You can also run the Squids active-active.

Trickier unless the servers have different names and redirect to their
name for the session.

If you set up LVS to use sticky server selection forwarding all requests
from the same client IP to the same Squid, and each Squid using one server
only then something like this would be acheived.
