So all of these are totally different systems/APIs?
If answer is Yes, then I see 2 options
1. Use a callable function (go to next step => search callable recipe by workato) because if using callable function you will not hit the HTTP connector limit, basically you can have as many callables as you want.
a) Create a callable function for API 1 - use whatever authentication method required for this API, create parameters that you need to push to this callable recipe, call the API then return the result back to the MAIN recipe
b) repeat the same steps 4 more times until you have 5 callable functions, each calling their own api, accepting their own Parameters and return Result
2. Second option is to use HTTP to 5 different APIs but create a "generic" http connector which has "Authentication" NONE and authentication using HTTP headers manually for each call. This will be messy as its not very reusable. For reusability/Best practice I recommend option 1, use this option only as last resort, as pointed out by Joseph above.
