Just wanted to agree with what everybody else is saying. The cats are in another new environment, and simply scared. They will get used to things and settle. However the sudden sprinting around the house in mad dashes is normal cat craziness
Whenever we bring home new kitties, i set up a littler box, food and water dishes, and a blanket in a bathroom and keep the door closed. Then we simply used the bathroom like normal, but pretty much ignoring them in there the first few days. Then we start making special trips in there to just sit on the floor. Let them get curious and come to you. Just go sit and read, or just sit and watch them, but don't chase them around or try to pick them up. You want it all to be on their terms. After a few days of that, they usually are warmed up to us and excited for us to come play with them! After that, it's letting them come out to other rooms to play for short periods to learn the house, with longer play periods each day. After a few days of that, they're good to go to have free reign. The general Idea is that they feel safer in smaller space at first, and you going in the room with them to just hang, lets them know you're friendly and not going to hurt them. So they'll warm up to you the more you hang out in there with them.
My experience doing this has only been with younger kittens, so I'm not sure how the mama will do, but I suspect she'll be on board before too long as well. Congrats on your new babies! Enjoy the kitty life!
