Slight morphological adaptation should not confuse you. In all the characters, morphological, anatomical and physiological they are bony fish.

Because they belong to the class Actinopterygii. Actinopterygii means "ray-finned" because the fins of these fish are webs of skin comprised of bony or horny spines. If you were to stretch a seahorse out and lay it flat, aside from its spiny exterior and pointy snout, it does look like a fish.
Salmon, tuna and other such bony fish, while they may not LOOK like a seahorse, they also belong to the class Actinopterygii. In fact, most bony fish belong to this class.

Because they are fish. Highly specialised and unusual fish, but fish nevertheless. They are closely related to pipefish, which are similar but straight, and leafy sea dragons, which are even stranger.
