We are in the process off procuring a project using nRF52, and I need to find out some important things. Are there any costs in using any of the libraries or SDKs from Nordic, for example, the SDK Thread?
That is correct. nRF52840 is the only supported device for Thread. Thread runs on the IEEE 802.15.4, and nRF52840 is the only device that have support for IEEE 802.15.4.
