It depends on the phalanges in question. The distal phalanges in the four fingers and toes articulate with the intermediate phalanges. The intermediate phalanges articulate with the proximal phalanges and the proximal phalanges articulate with the metacarpals of the hand and the metatarsals of the toes. The same is true for the thumb and big toe except that neither one has an intermediate phalanges.

Yes human fingers do have bones, there are three in each finger.

One of each of these in each finger starting at the tip.

distal phalanges, intermediate phalanges, proximal phalanges

But fish fingers should be bone free.

The radius is proximal to the phalanges. The phalanges are distal to the radius.

The radius is proximal to the phalanges. The phalanges are distal to the radius.

The phalanges. Each finger has a proximal (closest to the hand) and distal (furthest) phalanx, the second through the fifth each have a middle or intermediate phalanx.
