I’m planning to place two or three flashes on a stage and trigger them from the back of the room using a Canon ST-E2 on camera. I’m considering Yongnuo YN-565EX flashes set as optical slaves and want to know whether they will support TTL metering in this setup. I’m also concerned about how reliable this may be over distance or in a live event environment. If this setup isn’t dependable, are there better alternatives in a similar budget range?

Yongnuo claims that it will; whether or not it will work reliably in your situation will be a matter of experimentation. Off-brand is off-brand, and compatibility/reliability are always a little bit hit-and-miss. When it hits, you're golden, but there's always a question of forward-compatibility, so what works wonderfully today may not work tomorrow. Still, if you can save something on the order of $500/unit, expediency today may make a lot more sense than 100% compatibility with your next camera.

The Yongnuo YN-565EX is claimed by Yongnuo to work as an E-TTL optical slave with a Canon ST-E2, so in principle TTL metering should work.
The bigger issue is reliability. Third-party flash compatibility can be inconsistent, and how well it works in your stage setup will depend on real-world testing. Optical wireless systems like the ST-E2 can also be more hit-or-miss depending on distance, positioning, and whether the slave sensors can clearly see the commander.
So: yes, it may work, but you should experiment before relying on it for an important event. If it works in your current setup, it can be a very cost-effective solution; just be aware that third-party compatibility and future camera support are not always guaranteed.
