The AIP module will not participate in the ASA HA. However, if your ASA is running in Active/Passive HA failover, you would need to have the same module installed on both ASA, otherwise, the ASA HA will not work.
The AIP module works independantly of each other, ie: config will not be replicated between the 2 AIP modules. You wuold need to configure each AIP module independantly.
You would also need to have IPS subscription license for each module so you can update the signature to the latest signature packs (signature is released every few days).
Hope that answers your question.
