How many electrons does silver delocalize in a metallic bond? Since silver has the highest electrical and thermal conductivity of all metals, I suppose it delocalizes the electrons in its 4d subshell too?

silver has a high electrical conductivity not because it delocalises many electrons, but because its electrons are relatively easy to delocalise. (i think so, i've no idea myself about transition metal elements)

since in a metallic bond there are positive metallic cations and negative electrons, you should look at its oxidation states for the charge of its ion, which ranges from +1 to +3.

Interesting. Thanks!
