Fish Aficionado
A 5 gallon tank would be the absolute minimum for a Betta, provided he's in there alone.
Moving your others to your 10 gallon sounds like a good idea.
However...please try to lose the thought of How Many Fish Can I Pack Into A Tank?
The internet is full of suggestions and formula for working out just how many fish a tank could hold, but these NEVER really take into account individual fish needs. Many realise the efficacy of good filters and the benefits of frequent water changes, but this has people believing they can pack a tank.
People can and keep it all very nicely balanced, especially if they know what they're doing. Unfortunately, the higher a tank is stocked, the less 'wriggle-room' you get, if things start to go awry.
I often refer to speed limits. Here in Blighty, the National Speed Limit for many country lanes can be 60mph. That said, it would be suicidal to travel at those speeds, simply because you can. You'll never know what's just around the corner and, at 60, you'll be dead meat, alongside whatever poor soul you just happened to plough into. At 40, you have a chance.
