Can I manually tin them with solder specially the BGA's. Will that improve the solderability? What about corrosion of the copper? will it be prevented with the above process considering that after tinning of solder the solderability became acceptable

First, how oxidized are these solder balls? Will the take solder using your routine flux / paste? Second, on restoring solderability, the three basic methods you can use to restore solderability on components are: * Highly active fluxes in a retinn

Tenting a via refers to covering via with soldermask to enclose or skin over the opening. A via is a hole drilled into the PCB that allows multiple layers on the PCB to be connected to each other. A non tented via is just a via that is not covered with the soldermask layer. Leaving these vias exposed or covered has pros and cons depending on the your design and manufacturing requirements.
