What type of antenna are these.

hey, guys. I'm new to here. this is my first post at ifixit.

I have an old, outdated android device, MOTO DEFY. I'm trying to hack into the motherboard.

for some reason, I need to know What kind of antenna are these:

1. Ok, first I already know the BLACK one is baseband antenna. It transfer GSM/GPRS signal from ''SKYWORKS SKY77529 TX'' through a cable. It seems the BLACK antenna only TX signals, Does it have a RX effect??
2. The GREEN one, I assume that it is a GPS signal RX antenna. only RX the 1.5GHz GPS satellite navigation signal. Am I right?
3. The YELLOW antenna, I don't know what type of antenna is this, only TX signal?? or a TX/RX antenna. well, I don't have a clue.
4. The PURPLE antenna. Is that a spring antenna?? For what purpose?? Bluetooth/WIFI TX antenna??
5. The RED antenna. I have no idea. My best guess, Bluetooth/WIFI RX antenna. For RX only?? As you can see it on the image, the lower solder pad is connected to the GND?? Why??

I hope someone can answer my questions, I really appreciate your help, thank you.
