1: cellular antennas are the top and bottom bezels themselves, the charge port flex are also part of the lower antenna and dynamic tuner. The top antenna connects to the board with screw posts. GPS antenna is the top bezel. WiFi antenna is the top bezel, the one at the lower speaker and the top left of the phone. BT may switch between top and bottom WiFi antennas or just stay at the top. NFC antenna is the top bezel, connected to the board via screw posts and short flexes near the rear camera. 2: if you want to use the hotspot, you will need all those antennas. Antennas on modern phones are highly integrated, you can’t reliably remove one feature without damaging others.
