The trio were part of a young Wales squad that impressed on day two of the competition, after a challenging opening round of fixtures.
After a narrow defeat to France, Wales bounced back with a gritty win against Zimbabwe followed up by a convincing 31-7 victory over Japan.
"It's been a good two days in terms of learning and experiences gained for these young boys," said Head Coach Richie Pugh.
"To finish with two wins - especially the last one against Japan, when we actually executed our gameplan and played sevens - was pleasing, and we scored some nice tries.
"I hope now that they can take confidence, regardless of who we have in our pool in Cape Town next week, and push on,” he added.
“I don't want us to go back into our shells. The confidence we showed against Japan was the difference; to pass the ball with width and really attack their defence."
With just 103 World Series caps in their squad, Wales were the second most inexperienced side in the tournament, and Pugh emphasised the developmental nature of the process.
The challenge they faced on day one looked even more difficult in hindsight, with pool opponents New Zealand and USA making it all the way to the final.
"It's a case of lessons learned. It's been intense at times, and emotional too because the boys don't like losing. None of us do. After four losses it can get difficult and it shows the resilience of the players to be able to bounce back like they did and get the two wins today."
Wales now travel to South Africa for the second leg of the World Rugby Sevens Series.
