Is this hard to fix DIY? (photo incl)

The bank accepted my offer. I'd like to fix these myself to save money, but I have no experience. I thought since their small areas they might be doable:

Tile work isn't very hard, the hardest part will be finding matching tile and grout.

Pull up the broken tile with a hammer and chisel. Make sure to remove as much of the old thinset as you can. They make small hand tools for clearing grout lines that can help you get right up to the edge of the other tiles.

Mix up some thinset using the instructions on the bag, then, using a 1/2in notched trowel, spread thinset over the area with the flat side, then use the notched side to make ridges. Put a thin layer of thinset on the back of the tile and press it into place. Make it flush with the surrounding tiles by pressing it down or adding more thinset under it.

Give it 24hrs or so to dry, and mix up and apply grout using the directions on the bag. Other than the wait time, it should only take 2-4 hours.
