In Pathfinder, everyone fights on their own turn, independently. They have a certain number of attacks and can direct them at targets as they see fit. (Assuming no rules specific attached to a given attack that limits how it can be targeted.)
This means that the PC facing multiple opponents will get one or more attacks out on their turn, and then every other enemy will get their own turn to attack the PC, before the initiative cycles back to the PC:
Example: Initiative was rolled, with the Dire Wolf winning initiative, but the six regular wolves rolling worse than the PC. The Dire Wolf will go first, then the PC, then each wolf. The PC has two attacks per round due to two-weapon fighting.
Dire Wolf: attacks the PC with its bite and hits. It gets a free trip attack that must be used against the same target as the successful bite; it misses.
PC: attacks the Dire Wolf twice, hitting twice and injuring the Dire Wolf a bit.
Wolf 1: bites at the PC, hitting.
Wolf 2: bites at the PC, hitting.
Wolf 3: bites at the PC, missing.
Wolf 4: bites at the PC, hitting.
Wolf 5: bites at the PC, missing.
Wolf 6: bites at the PC, missing.
Now that everyone has had their turn in the initiative order, it rolls back around to the "top of the round", starting with the Dire Wolf. The PC has been bit a lot, and has only managed to slightly injure one opponent.
(Yes, being outnumbered is bad.)
