Three ways:
1) Stupid, and long: Copy file, delete all tiles what you dont needed.
2) Smart, but hard: Unzip *. Pyxel, find tile what you want. Open Pyxel file -> import -> tileset. Change tileset size like your tile, check import to new (or current document if needed) and voila.
3) Smart and easy, create tileset from tiles what you want, export it to image, and insert in Pyxel like tileset in previous variant.
