Had the opportunity to test this out today, and long story short, Thai Airways does indeed stick to the one guest limit. However!
In our case they let two kids in for the price of one extra guest, bringing the cost down to a rather reasonable US$20/child, so two thumbs up to Thai. Singapore Airlines, are you listening?
...although I have to note that of all the varied food offerings in the lounge, both offspring said their favorite was the Mama cup noodles. Given that these retail for around 12 baht a pop, you'd need to eat 100 portions to pay off the guest fee!

Lounge availability during Covid period may change without notice. So please plan ahead.
As a matter of policy you can bring one guest. Period. You may try your luck at entrance maybe you are lucky. If not you can try King Power lounge which is accessible to member. You can apply by top up your account for 2,000 Baht and use that credit to purchase things at their shops at airport.
