Mhm i say clara would be a starfruit, sweet-sour is a good way to describe her while looking cute hahah and considering they look like stars when cut = moon brought her here, feels right she would be one. Oh and christmas is a big theme aka the golden star! so yeh

Lennox would be a plantain bcuz uh green,grow on tall trees(similar to bananas) , their skin is pretty hardy and despite being starchy and not as sweet if you cook them they can be so sweet! just like lennox apparance haha scary at first but a total sweetheart. Plus their also my favorite fruit bcuz i can make tostones my beloved tostones....

Twins mhm i say a pomegranate, the fruit they offer on their location stories reminded me of one+ i always hc oz,figaro and the twins have greek inspo to them in someway with the twins being hades(undead thematics+ the oldest) so i had some point just associated that fruit to them hahah.
