B - trigger from enemy creature going to the yard (remove bridge)
Y - trigger from your enemy creature going to the yard (create token)
Z - trigger from your enemy creature going to the yard (create token)
The stack should look like this:
A goes to the stack:
"A - remove bridge"
B goes to the stack:
"B - remove bridge"
"A - remove bridge"
Y goes to the stack:
"Y - create token"
"B - remove bridge"
"A - remove bridge"
Z goes to the stack:
"Z - create token"
"Y - create token"
"B - remove bridge"
"A - remove bridge"
At this point, if both players pass priority, the first item on the stack will resolve, meaning resolving Z will net you a token.
After resolving Z trigger, the next item on the stack is the Y trigger, and you get another token.
After you get all your tokens, you resolve the triggers for removing the bridges due to an enemy creature hitting the graveyard; triggers A and B respectively.
tl;dr - all the bridge triggers go to the stack at the same time, so you can arrange them in the order that benefits you the most.
