At 10 months old he still is a kitten and still has a chance of outgrowing some of this behaviour.

Have you or your family played with him using your hand or feet as targets ?

What about playing with fishing rod toys with him to distance him from your hands/feet ?

When he bites I would ignore him completely, lack of attention is a true punishment for kittens. I don't use water sprays myself.

What about adopting a similar aged friend so they could bite each other (joke) but another cat may help your cat behave better.

Good Luck.
