Dear Inderjeet Ji,
The First to images seems to be of Daldinia but to confirm it to D concentrica just you have cut in to have this specie has a diagnostic concentric growth ring like formation. If you find there is concentric ring this is undoubtedly D concentrica, but quit hard to determine from outside.
The next two photos of the white fungus growing on the bark surface seems to be Corticium galacticum commonly found growing on the surface of decorticated wood.
The polypore member can be some species of Ganoderma hope the upper surface of the basidiocarp is maroon in colour as it seems partially.
Forwarding again for Id assistance please.
