RE: Can I use both UUIDs 16 bit and 128 bit in one project

Yes, you can certainly use both 16- and 128-but services in the same project.

If you search the SDK for "sd_ble_uuid_vs_add", you will find some examples.

Basic API's for creating your own 128-bit service
- sd_ble_cfg_set(BLE_COMMON_CFG_VS_UUID, ...) // Configure BLE for your vendor-specific services
- sd_ble_cfg_set(BLE_GATTS_CFG_ATTR_TAB_SIZE, ...) // ensure attribute table is large enough
- sd_ble_uuid_vs_add() // Create a vendor-specific base UUID
- sd_ble_gatts_service_add() // Add your service to the GATT server
- sd_ble_gatts_characteristic_add() // Add your service characteristics to the GATT server

The examples demonstrate how to hook up your service with the BLE runtime events.
