I build many 2 node clusters in the past without any issues. Do note that when you need to perform an upgrade of ESXi you will be running temporarily without protection for your VMs... Because if you are doing an upgrade that host will probably be in maintenance mode and won't be used as a fail-over target. Hence many people will recommend going with 3 as the minimum. Nevertheless, two works fine.

Yes it is possible to have a HA cluster with just two hosts. You should make sure the each host has the capability of running all the 10VM's at a time in case of a single host failure.

Check out the HA checklist here VMware vSphere 5.1
