Curiously WordPress does recognize multiple plugins in a directory, but results can be highly unstable. It also wouldn’t be possible at all if plugins had overlapping file names inside.
I wouldn’t recommend you attempt this by literally putting them together in a folder and going through installer.
You don’t quite cover your situation in detail. The reasonable solutions I could thinkg of would be:
- uploading and extracting zip with the plugins directly
- using WP CLI command to install them quickly from remote URLs
- making a small plugin that will install these four (and possibly delete itself after)
