Repair crumbling mortar in round brick stairwell to front door

Hi. I am wondering if it is possible for me to fix this porch on my own. If so, what all is involved? As you can see, the mortar is crumbling. At the beginning of the summer I only noticed a little and it has grown quickly.

Tuck-pointing is not very difficult to do, but it's very easy to do improperly. The most difficult part is removing enough broken or debonded mortar to enable the new material to stick. I'd recommend using a small angle grinder, while wearing a good dust mask, because it generates a lot of dust (loaded with silica, which can cause mesothelioma if enough of it enters the lungs). If you haven't done so already, google tuck-pointing brick, and read/study all of the how-to information available. Then make the decision to do it yourself, or pay someone else to do it.

will current mortar adhere to new mortar?

So, I understand that I have to take out the old and crumbling mortar before putting in new. What about the areas where the old mortar is intact - but separating from the brick on one end. (see photos). Can I just fill in along that end with mortar?

You really need to remove that mortar so there is enough area for new mortar to be able to attach it self to the brick. You'd either grind it out like Bridgeman suggested or chisel it out.
