Let's summarize:
- United Club individual membership: UA clubs only, no guests
- Chase United Presidential Plus credit card & Chase United Club credit card: United Club individual membership, plus one guest and dependents under 18.
- Chase United Presidential Plus credit card & Chase United Club credit card with Premier Gold or higher: United Club individual membership, plus up to two adult guests or one adult and dependents under 18 AND Star Alliance lounges (to be honest, this addition is just what you get because you are Star Gold)
- Chase United Presidential Plus credit card & Chase United Club credit card with $50,000 spend: United Club individual membership, plus up to two adult guests or one adult and dependents under 18 AND Star Alliance lounges
I think these are all the options currently, yes?
