The Key Combination for a WoW Macro Action is used by the ISBoxer Addon, to bind the macro you define, to the given keystroke. You do not want to double up on a Key Combination; only one of the macros would work.

The ISBoxer equivalent to Jamba tags is Action Target Groups (ATGs for short); you can create an ATG by right clicking "Action Target Groups", rename it (e.g. to "rets"), and then drag characters to it from the top pane into the bottom left pane. The way Tags work in Jamba, the command gets broadcast to all of your characters through the in-game Addon channel (note: this is dependent on your ping to the WoW server, Addon communication throttling, etc), and is ignored by the ones that don't have the given tag. ISBoxer sends keystrokes directly to the target windows instead (note: this is NOT dependent on your ping to the WoW server), which might be interpreted by the game as a WoW macro. So for example instead of sending "/jamba-team setmaster holypaladin rets", you can make your macro in ISBoxer "/jamba-team setmaster holypaladin" and send it to the rets via an ATG.

If you want your guys to follow someone besides the guy you are playing, you will need a different version of the follow macros. Without strobing, it's a matter of making a copy of "FTL Follow Me" and changing a couple details. An undocumented feature of the ISBoxer Addon is that when you /follow, your follow strobing target is automatically updated to whoever you're following -- so if strobing is already on, all you need to do is issue a follow command. That makes it easier to leave strobing on and have them follow whoever you like. So make a copy of "FTL Follow Me" in the General key map, and do the following: change the Hotkey to something else, leave the Key Combination and the macro as-is, and change the Target of the action to whoever should do the following (not the person to follow... for example, "others in" an ATG called Rets). Then you can make them follow any given character by using a Do Mapped Key Action, pointing to this new copy of "FTL Follow Me", with the Target of the action set to whoever they should actually follow (it should only be ONE specific character!)
