The reward for winning each duel are as follows:

Deadeye Duncan
Speak to Ajuur and tell him you're ready for a duel:

Even at level 2 on Difficult, you shouldn't lose to him unless you're actually trying to throw the match (maybe because you feel sorry for him?).

If you do lose:

If When you win:

Speak to Ajuur to receive your percentage of the purse:

Gerlon Two-Fingers
Speak to Ajuur and tell him you're ready for a duel:

He's more damaging in melee combat, so maintaining distance is advised unless melee combat plays to your strengths as well. However, he shouldn't be difficult to beat even if saving levels on Difficult.

If you lose:

If you win:

Speak to Ajuur to receive your percentage of the purse:

Ice
Speak to Ajuur and tell him you're ready for a duel:

Her ranged and melee abilities are fairly balanced, so play to your own strengths.

If you lose:

If you win:

Speak to Ajuur to receive your percentage of the purse:

Marl
Speak to Ajuur and tell him you're ready for a duel:

Marl is an exclusively melee fighter, so grenades aren't normally a good idea: either he'll run out of range, or you'll also be within range. If you cannot stand toe-to-toe with him, running and gunning works, although you should avoid using Power Blasts or Sniper Shots as their longer animation outside the framework of combat rounds gives him more time to close to melee range.

If you lose:

If you win:

Speak to Ajuur to receive your percentage of the purse:

Twitch
Speak to Ajuur and tell him you're ready for a duel:

Twitch favors two Heavy Blasters and he can use Rapid Shot, so closing to melee range and obliging him to draw his Vibroblade is recommended. However, if you're saving levels or have low chance to hit, you may prefer to maintain distance, using shields to negate damage and grenades to inflict it.

If you lose:

If you win:

Speak to Ajuur to receive your percentage of the purse:

Bendak's Bounty
Once you've become Taris Dueling Champion, you can go to Bendak in the northeast corner of the Upper City cantina's Pazaak room and agree to meet him in a deathmatch, giving you an opportunity to kill him and then collect the bounty from Zax in Javyar's cantina in the Lower City.

To save time, you should follow him out of the cantina and then return, before talking to Ajuur.

If you speak to him again without leaving the cantina:

After leaving the cantina:

You're not committed to the death match until you make the following response:

Run! The first thing Bendak does is throw his Plasma Grenades. He'll stop once you're in melee range, but if you're not confident enough to go toe-to-toe with him then keep running around the arena until he's thrown all three.

The number of credits you receive depends on how persuasive you are, or your willingness to move closer to the dark side of the Force:

Otherwise:

Should you speak to him again:

Nothing remains but to go to Javyar's cantina in the Lower City to collect Bendak's bounty...
