Asking about how many service limit of instance type

I'm working on how to use auto-scaling feature of my fleet. I made a request to increase service limit of c4.large through customer service of AWS and then I got how the auto-scaling feature in GameLift worked. So my question is that how many service limit of other instances apart from c4.large I can request?

I extract something from FAQs below.

For this example, we calculated costs in the US East region (N. Virginia) using Linux as our operating system and 2 CPU cores and 3 GB of memory for our servers. At peak demand, we assumed we needed 2,500 instances running. These inputs result in a 3-year total compute cost of about $4.5 million, or roughly $125,000 per month.

Can I request 2,500 instances through customer service? However, the picture below, shows service limits. REMOVEDUPLOAD

Any help is appreciated.
