Preheat oven to 325 degrees F.
Combine milk, coconut milk, and coconut cream in a saucepan. Stir, bring to a boil, lower heat, and simmer for 15 minutes until slightly reduced. Remove from heat and cool for 5 minutes. Add toasted coconut and infuse for 15 minutes.
To make the caramel: combine the sugar, water, and lemon juice in a medium saucepot and cook over high heat, without stirring, until it darkens to amber. Pour the caramel evenly into 6 (4-ounce) ramekins and set aside.
In a bowl, whisk together the eggs and the yolks. Strain the milk mixture into the eggs and whisk to combine. Fill each ramekin with this mixture, then place ramekin in roasting pan. Create a water bath by filling the roasting pan 1/3 way with hot water, and cook, covered with foil, for 25 minutes. Allow to cool before serving.
To unmold the flan: take a paring knife and run it around the sides of the ramekin to loosen the flan. To help it along, you may also place the ramekin in a shallow bowl with warm water until it comes halfway up the sides for a few seconds. Invert a serving plate on top of the ramekin and flip over to unmold.
