AnswerHQ stands for the headquarters. It is generally made of your best character, and his/her retinue if one is allowed.
Well you'd have to make the model for him, then you could drop him in game with whatever stats of other HQ you'd want. Eliphas isn't a mentioned or special character in 40k TT, so you'd have to choose of which HQ do you want for his stats. Like Abaddon, or Kharn for good examples.

AnswerFirst you must have 1 HQ and 2 troops, after that you can expand with additional choices (1 HQ, 4 Troops, 3 Elites, 3 Fast Attack, 3 Heavy Support, 3 Super Heavy).

Points in warhammer 40k are based on how good a person is. An HQ unit is better than the normal people of the army and is therefor more points. you also add points to things to give them better weapons or special powers.
