Family Members Hearing Someone Call Out Their Name

Quite possibly evil spirits. Someone there opened up something to evil spirits. Say this. Leave this place at once unclean spirits by the blood of Jesus Christ. Shout that out. If the spirits don't leave then you may be in trouble. You may need a Catholic Priest.

Do you hear these voices as you're about to fall asleep at night? If you hear voices like whispers in the night as you are in bed, half-asleep...do't answer to them. It's evil spirits trying to lure you into a trap. Better safe than sorry.

Is there anyone in your house that can see spirits? Or anyone that seems to be able to just "know" things from nothing?

It is most likely a ghost. All land has 'predecessor energy' so it does not matter if the house is new, old or remodeled. All ghosts are lost souls that are stuck between dimensions and they need help! I cross ghosts over all the time as they are presented to me. This prayer is AMAZING! It really works to help the dead. Plus you earn a ton of karmic brownie points for this huge spiritual service that you provide. Say this prayer like you mean it at least 3 times whenever you sense the presence of a ghost. You can also say it at night before bed so that you get a better night's sleep.

Hello omm,
This sounds like a ghost. He or she could be someone who died while in fear or pain, but I am not certain this is the case. Perhaps you have two, because they have been heard as a male and female voice.
It puzzles me that they ask for the door to be opened, as though they want to be let in. If they are looking for help as they were in life it is possible they are confused about being ghosts. That may sound strange, but it is possible.
Because they call your family by their old nicknames, I wonder if they could be friends who knew you some time ago in life. If you had lost contact with them and were unaware of their deaths, this is another very bittersweet possibility. If they are old friends they may have come for a visit or to watch over you. Perhaps they are spirits who've been with you for years and were not able to easily follow when you moved. They may be trying to let you know they have found you.
Whoever they are, they are strong if they are able to speak aloud.
If you feel they are not a threat, it may be a good idea to attempt communication. I would advise you to have someone else in a distant part of the house when you try speaking with them. The voices seem to come when a person is alone, but it would be wise to have someoneelse in the house with you so that you feel safer. The easiest way to try ccommunicating in this case would be to respond to the voices. You may want to ask who is there or simply say hello. You caniintroduce yourself or say anything you want. Be patient and do not be discouraged should a response not be immediate. If anyone in your family has a type of psychic ability, I would suggest that he or she try to feel the essence of the spirits. You may even ask a psychic to come to your home for this, although it may not be necessary. Mental communication is usually easiest, sending thoughts.
You may decide to approach or answer the door if asked again. I am unsure whether this is a good idea. All of this depends upon whether you begin to feel threatened. So far I believe you are safe in your home. Most ghosts mean you no harm and can even become friends.
Best of luck,
Nightingale

You said your house is newly built. Often, construction work can 'awaken' sleeping spirits. So maybe you should check up if that plot of land has witnessed any malevolent death. Also, 3.30 am which you said has been the times of these incidents, is said to be the most active hour for spirit activity.
