I generally only enter for myself. But occassionally, I'll drop my better half's name in the hopper. The rules usually tip me off if that is okay. If it says one entry per person/email without other restrictions, I go for it. If, however, it further states per address or household or phone number, I don't go there. little caveat. In a local promo, the print media (it is a phone entry sweeps) says, one per person/household address. When you call in to enter, it tells you, one daily entry per phone number (I have four for business). When you go through the data fields for entry, it asks for the address. I enter one number only.
