Kitchen countertop outlets should be GFCI.
It may be possible to use a GFCI outlet to protect outlets downstream.
If you change an outlet to GFCI - they take more volume. You may have to very carefully fold the wires into the box to efficiently use the space. (You may have to do that with other outlets too.)
If there is not a ground wire to the outlet it may be best to come back and describe what you have. For example, a metal box may be grounded and a "self grounding" outlet can be used. If there is actually no ground, 2 wire receptacles (with no ground) can also be used.
