To be honest they're probably not even worth filling.
Chip 1 there is wood showing but it is still covered by resin so the likelihood of water getting into the core and doing any damage is extremely low probably none. Maybe if you wanted to be super safe you could put a bit of epoxy on it but it's probably not even worth the effort.
Chip 2 there is no wood even showing and that is a purely cosmetic chip.
If these chips become larger and the wood is actually exposed meaning water can get into it then sure go ahead and put some epoxy on it, you just need to cover all the wood and any exposed inner bits of the ski with the epoxy.
I used to be like you when I got my first pair of skis and I was super paranoid about trying to fill, sanding and trying to fix every little chip and scrape. But over time I realized that if I am going to be aggressively skiing park or even dropping cliffs, skiing off groomers I am going to destroy my skis no matter what and it's not really worth the time or effort to go and try fix all these little chips.
What are you using these skis for? If you're skiing park or big mountain they're going to chip because inevitability they will get bashed together on rails, in the air doing grabs (blunts and mutes particularly) and landing with one ski on top of the other will cause them to chip like what you have posted. At the end of the day skis used for park or aggressive big mountain skiing will probably only last you a season or two and so just enjoy the skis and don't worry about wrecking them. Chipped up and thrashed skis look sick anyway, wear you battle scars with pride.
