Proxy for Virtual Box running BlueStacks for Instagram?

Hey! This is my first post ever on BHW. I've learned so much in the past few days here.

I have a question which is driving me crazy.

I would like to make a setup wherein I can have various Virtual Machines running at the same time each with different proxy. Within these Virtual Machines I will use BlueStacks to run Instagram.

The setup would be like this -
VM1 > BlueStacks running 2 Instagram Accounts - Proxy A
VM2 > BlueStacks running 2 Instagram Accounts - Proxy B
and so on.

I would want to run 10 VMs so I'd need 10 proxies.

1. How do I set it up?
2. And where do I find the best proxies for this purpose of VM and Instagram?
3. Is is possible to have 2 VMs running on one proxy?
4. Is is possible to run more than one instance of BlueStacks on 1 VM? (Disregard using Parallel Space)
5. Finally, can my PC handle running 10 VMs 24x7? I have i7 3.7GHz, 16 GB, 512 SSD. If not, can this be achieved using a VPS?

Running 10 virtual machines on your pc is a lot... You'll definitely need a vps.
Yes, im quite sure you can run multiple vm's on a same proxy.
No, I dont think bluestacks supports multiple instances.
Just use search to find people who sell proxies.

And you ask how to set it up? I dont know whats there to explain, rent a vps, install vm's on it and then just install bluestacks on the machines. And make sure to use proxies.

bluestacks loves RAM . so make sure you have alot of this beforce you start your journey
