Its really depend on you as you may have upto 50 accoutns with 1gb each but then u need to consider you bandwidth which will be shared b/w all these plans.
In addition to what others ahve said, you also have to consider what type of websites (and scripts) you're allowing your customers to host with you. Even if they're not using CPU and memory intensive scripts, with the memory you currently have, you have to make sure a customer or few are not spiking the usages in a consistent manner. Also check to see the ease of upgrade from one VPS to another VPS plan at your host and the overusage fees. Based on those, assign the disk space and bandwidth accordingly (and/or sparingly). Calculate the monthly fee you're paying for VPS with the combined reasonable package incomes and you'll see how many you can host. (Of course if you allow many databases or allow some usage intensive sites, you have to reduce the plan specs or increase price as well; it might reduce the total accounts hostable).
Its depend on how your shared hosting user use their hosting. If only use WP then you can create around 100 CPanel account.
If you have scripts such as forums, or sites with more than 20 concurrent connections it will struggle with only 500mb of RAM. What is the cost to upgrade it to 1GB? Probably would make it able to hold a few more sites then. Also if you only have 50GB, have you split part off into a backup drive? What happens if you need to backup an account? So in fact you will probably only have about 30GB of disk space for accounts, after you've taken the logs, cpanel, backups etc.
100 WordPress accounts, with only 512MB? No. 100 accounts with static content (.html), with only 512MB? Yes. WordPress is resource intensive. 512MB isn't going to be enough for 100 accounts unless all the accounts have no plugins installed and they all have caching enabled. Also, cPanel itself uses quite a bit, so 512MB won't get you very far. It would be good for 1-2 moderate size websites.
