Can I safely leave my new dog mom with her puppies to go to work?

Monitoring throughout the 8 week period until the puppies are weaned is recommended, yes, although it may be difficult while you are sleeping. Having the mom and pups in your room and setting an alarm to check on them a few times a night is reasonable. If you are able to get someone to watch them that's great. Otherwise minimize the amount of time they are left alone as much as possible, and try to get a dog sitter if you will be gone more than an hour. Breeding dogs is a lot of work, and it is important to keep track of the mom and pups' progress by checking on them frequently.

If the pups are kept warm, there is no problem with her staying away from the puppies for 1/2 hour. If she does not get stressed out by being away from them, you can take her for a walk around the block up to 1/2 hour and later on even longer. It is important that the puppies do not get cold. It is best to take her out after the puppies suckled, and now are sleeping. Make sure they are in a box, so they cannot start crawling around when mom is gone.

I would not leave the puppy with her unattended. You will need to let the puppy suckle every two hours under supervision. If she eats her puppies, it may be a good idea not to breed her again, as "bad" mother instincts can be hereditary.

Yes, it is possible for you to go out for an hour or two to go to dinner and run some errands. I would check on them every couple of hours, but that doesn't mean you have to stop your life. I hope this helps!

It is normal for the female dog to have a break every now and then, as she will have to go to the bathroom, get some food, or simply want to move around. As long as she returns to the puppies and isn't gone a long time, there is nothing to worry about.

It would be best to keep momma dog and puppies separated from your other dogs, at least for a time, as new puppies around other dogs can be a cause of high tension and stress for the mother dog. With all the hormones from birth, plus protection of puppies, a normally friendly dog may accidentally harm another dog in the household in an attempt to protect her puppies. Once the puppies are old enough, you can then gradually introduce your other dogs to them, under direct supervision.

Make sure that the new area is cleaned before you take the puppies there. Fleas can be left behind by previous pets as can worm eggs and parvo virus out in the yard. Odds are, everything will be ok but know that anything is possible. Make sure to move mom with her babies. I hope this helps!
