TL;DR Your panel should be fine for GFCI/AFCI but I wouldn't bother unless this is the easiest way to add GFCI for kitchens/bathrooms.
The typical problem with replacing regular breakers with GFCI/AFCI breakers is with "half-size" or "tandem" breakers. These are where a standard breaker "space" is split into two breakers in order to double capacity without requiring a full redesign of the panel. Your panel appears to have only 6 spaces (which is super-small, but that is a separate issue), with full-size breakers currently in all 6 spaces. So there should be no problem replacing some or all of those breakers with GFCI/AFCI breakers.
That being said, there are some additional considerations:
- GFCI protection (which can be combined with breakers or can be combined with receptacles) is a huge safety upgrade for certain areas, particularly kitchens and bathrooms. As far as safety & effectiveness, breakers vs. receptacles makes no difference. However, GFCI receptacles are much more convenient than GFCI breakers, and often cheaper too.
- AFCI protection is generally more effective the sooner in the circuit that it is done - e.g., AFCI breaker better than AFCI receptacle. There are some exceptions, particularly if you have wire inside metal conduit.
- In general, GFCI and AFCI are not required unless you are adding or changing things. Simply "just because I heard it is better" is OK, but not required by code. That being said, GFCI is a life-safety upgrade that can help even if you never change anything else about your electrical system. On the other hand, much of the benefit of AFCI has to do with damage to wiring, old connections wearing out/getting loose (e.g., backstabs), etc.
- If you put in GFCI/AFCI breakers, you rule out the possibility (depending on the particular panel specifications) of doubling up using tandem/half-size breakers to add more circuits.
- GFCI is of almost no relevance for the "Kitchen Lights" and "Main Lights" breakers, assuming those labels are correct. AFCI could still be useful.
- GFCI and AFCI may actually be contraindicated for the "Fridge" breaker, assuming that the only thing on that breaker is the refrigerator. That is because GFCI is of almost no relevance for a refrigerator, and both GFCI & AFCI protection should be balanced against the damage (spoiled food) from an unnoticed breaker trip.
- AFCI is reasonable for all the circuits except the "Fridge" circuit.
- GFCI is reasonable for "Outlets" (especially if that includes the bathroom) and "Outlet AC" and a very good idea for "Kitchen Outlet", provided they are not already protected at the receptacles. Having double GFCI protection (breaker and receptacles) does not improve safety and can complicate things when there is a GFCI trip.
