Absolutely, but the scale of the balloons is a bit off. Nobody would be walking shoulder to shoulder like this. For a normal-ish 170lb/77kg individual your personal balloon would have to be a little under 6.5 meters across assuming it were filled with helium.
Sure. You could do a cylinder of three quarters of a meter across which seems like a reasonable footprint for someone to stand in. That’d only have to be, uh, 325.5 meters tall to have the same volume.
Your asshole “buddy” constantly throwing sharp objects at your balloon causing you to be wet all the time and laughing as you ask your mom if she can mend your massive cylinder for the 13th time this month
It would, but less than the density difference, since you’ve removed weight from the balloon thus gravity has less of a pull on the balloon. My wife (a PE in thermodynamics) was the one that verified that comment before I posted it, hence why I didn’t say it would increase lift by the difference in density.
We do have the technology for this… right?

Yes, I did the math.
You did the basic math, with your spherical balloon. What about giant cylinders? Then you could really pack it in.

I fail to see the problem.

You could use hydrogen, which is less dense than helium. Then if it catches on fire like the Hindenburg you’d already be in the water.
It wouldn’t help. The thing that gives you lift is the mass of displaced air. Difference from the (lack of) mass of the lifting gas is minimal.

We thank you balloon master!
