Return of Reckoning

Is possible get by API Player health (value or percent) and target him (target friendly by APi - player name or group position, sc - from all groups, sc group members, party, warband) ?

I want get health data about all players from my side in:
scenario
party
warband

for Party:
PartyUtils.GetPartyData()

for warband:
PartyUtils.GetWarbandData()

for scenario/instance:
GameData.GetScenarioPlayerGroups()
