Yes, you can "give" someone a tech with the Set Tech Status effect. Set the player you want to give it to, the name of the tech, and then select ACTIVE.
As for the question about Relic Force, all of those choices are the different technologies that you can make the relic give. (i.e. if you force it to be "Copper Weapons", then if you garrison the relic in your temple you'll be given Copper Weapons)
