1. Can you tell me how I can call the stewardess?

2. Can you tell me how I can call the female flight attendant?
[Are both okay? Can we use both? Do you have other names for 'stewardess'?]

Both a grammatically correct, but I would go with stewardess. The suffix "ess" tells us that the stewardess is female.

Both are not okay. The word "stewardess" is rather out of fashion. Flight attendants are not just females any more. We would ask how to call the flight attendant without reference to his or her gender. Your grammar is okay in both.

stewardess is just about good

1. To call a stewardess on a flight, you can typically use the onboard call button located above your seat. Pressing this button will notify the cabin crew, including the stewardess, that you require assistance. Alternatively, you can also politely raise your hand and make eye contact with a nearby stewardess to get their attention.

2. Yes, both "stewardess" and "female flight attendant" are used to refer to the same role onboard an aircraft. However, it is worth noting that the term "stewardess" has become less commonly used in recent years, and many airlines now prefer to use the term "flight attendant" to avoid gender-specific language. This change reflects the diverse gender representation in the profession. Other gender-neutral terms used for this role include "cabin crew" or simply "crew."

It's important to keep in mind that language evolves, so it's always a good idea to refer to individuals using the terms preferred by the airline or the industry.
