Melt peanut butter with 2 teaspoons coconut oil in microwave until melted.
Melt 2 tablespoons chocolate chips with 2 teaspoons coconut oil in microwave until melted. Check every 30 seconds or so, stirring each time.
Slice apples into skinny wedges. Sprinkle lemon juice on them if not serving right away, coating all sides. This will prevent browning.
Arrange apple wedges on a plate and drizzle peanut butter mixture and chocolate mixture over the top. Sprinkle the rest of the chocolate chips, chopped walnuts, and shredded coconut on top.
