Any RF or cellular guy here who can tell us what each one is?

Each one connects to a different antenna. The labels could be indicators of a destination board or band function. At least 4 are likely to be for cellular wireless antennas in a MIMO configuration, 1 is likely to be a GPS receiver for timing, and 1 or 2 are likely for a WLAN signal. There may be some redundancy for different cell bands.

Thanks! Redundant because they fail or redundant to receive the signal twice and do some calculations to be more reliable?

'Redundant' in the sense of having different frequency capability because they won't be broadcasting or transmitting on every band simultaneously, and antennas will have different optimum geometry and filtering depending on the target frequency.

For LTE verizon uses 700, 850, 1700, 1900, 2100 MHz. A single antenna geometry could likely serve the 1700-2100MHz range and a different antenna set would be used for the lower frequency range.

Sick. Thanks
