Multiple Gerund questions

Apologies up front for a long post, but I am trying to improve my gerund knowledge and I need some guidance please.

Part 1 - Can you please confirm if these sentences are correct and their meaning:

1. I enjoy flying to see my mother. - A simple statement saying that I enjoy traveling via plane/helicopter to see my mother rather than for example doing a "driving" activity.

2. I am happy to fly to see my mother. - A confirmation statement confirming that I am happy to fly to see my mother.

3. I am happy about having flown to see my mother. - A statement describing an action that happened in the past that relates to now.

4. I am happy to have flown to see my mother. - Same meaning as #3?

5. I am happy to have been flown to see my mother. - A statement stating that someone one or/and a thing did the action by flying me to see my mother.

Part 2 - What is the difference between these three examples (specifically with gerund and prepositions):

1. She enjoys learning English. - A general statement about an action that is happening in the current time. it's unclear if it's happening at exact moment thought.

2. She enjoys having learned English. - Something happened before now.

3. She enjoys having been taught English. - She enjoys that someone taught her English in the past.

4. She is happy about learning English. - Similar to #1? If so, what is the difference?

5. She is happy about having learned English. - Similar to #2? If so, what is the difference?

6. She is happy about having been taught English. - Similar to #3? If so, what is the difference?

7. She is enjoying learning English. - Similar to #1? If so, what is the difference?

8. She enjoyed having learned English. - Does it mean that she is no longer alive? Or does it mean both actions completed in the past?

9. She enjoyed being taught English. - Similar to #8 but someone taught her in the past.

Cheers
