Can one remove and re-install the trigger/sear pin and the hammer pin in the same lower multiple times without causing some damage to the holes in the lower?
Also, if replacing a sear, for example, would one use the same pin or use a new pin?

If you are not ham-handed about it, yes.
As to replacing the pin - if it is an after market trigger group, I would use the supplied pins.
Sure, the pins are not disposable like roll pins are.
Using proper technique, it should take very little force to remove and re-install the pins.
This will not damage the lower unless poor technique is used and misaligned pins are hammered in.
Agreed--very little force is needed to install/re-install pins. Manipulate the trigger group by hand to make for more/less tension. Unless you're hammering them in, there's no reason you couldn't remove/re-install those things a hundred times without damage.
Thank you for all the responses.
A Geissele slave pin makes the trigger/disco a lot easier and I use a polished punch as a slave pin for the hammer. Makes life easy.
Don't use a hammer to smash the pins in.
A hard anodized lower should be pretty durable. If you built from an 80% and then used some sort of paint I wouldn't trust it as much.
Holes and lowers are damaged by people plowing into them with hammers and punches. It's all about technique. I generally use a Glock punch to push the pins out. Rocking the hammer back and forth helps when pushing the hammer pin out.
Thanks again for the very informative responses.
Ned Christiansen posted these a while back. I picked up a set and they are awesome.

Those do look like neat tools; however, I do have a set of punches that I think will work just fine with some finnesse on my part. Thanks.
The KNS hammer cage is also handy for installing/removing the hammer.
Yeah, I just use an extra hammer/trigger pin the line up the both sides....
