Each module has its own licence feature, and the Suite includes every module. Every licence is lifetime: you pay once and keep every future update, including new major versions. The licence is a signed file tied to your hardware, on up to two computers at a time, and verified offline.
You pay once and keep the software and every future update, with no upgrade fees. A licence runs on up to two computers at once (a research PC and a trading VPS, say), with the MetaTrader 5 terminals you list; you can move it as often as you like, yourself. See the licensing FAQ for the details, including how long the old computer keeps working.
They install together, but the licence gate checks each feature separately, so you can own one without the other. Alternative Data also needs two free API keys, FRED and EIA, that you register yourself.
Try any module free for 14 days, the same as the StrategyQuant X trial: get a key on the download page, see the trial policy. These are research and deployment tools; nothing here promises profit.
You also need StrategyQuant X, which is a separate product from a separate company and is not sold here. Payment is handled by a merchant of record that sends the licence key by email, and prices are shown before tax.
