Women enjoying exclusive favours in Jannah

Q: I always got amazed when reading about Friday markets in Jannah and what happens there and it got me wanting to do good deeds to enter paradise. However, I read somewhere that only men go to Friday market and women don't. The description of Friday market is very amusing and wants everyone want to be there but I feel heartbroken that even if I make it to paradise I won't be able to get there purely because I am a female. Why don't women get a Friday market? If Friday markets are only for men, then what do women get?

Performing fardh hajj or sending one's parents for umrah

Q: My husband and I wanted to do hajj in 2022. We have been waiting for this for three years.

When he was first time eligible for hajj, he sent his parents for hajj to get the reward and to give them a chance first. Due to the pandemic we were not able to go, now we want to go but his parents want him to send them for umrah.

What should we do now, give preference to his parents nafil umrah or to our mandatory hajj? 

Performing salaah while on the aeroplane

Q:

1. If I am travelling on an aeroplane, and the salaah time enters, then what is the correct way of performing salaah and what timing do I follow for each salaah?

2. If there is not enough space to perform salaah due to the aircraft being small, or the airline does not allow me to stand and perform salaah, will it suffice for me to sit in my seat and perform my fardh salaah?  

Having a Quraan khatam once a year for the deceased

Q: My in laws have a culture of performing Quraan khatam once a year for the deceased by having someone or a group reading Quraan and send esaale sawaab to the deceased father or Muslim family members. There is also intermingling of opposite sexes at the event. Cooking etc. and feeding the guests.

My question is, are all those efforts counted in the court of Allah, such as Quran tilwawat, dua for the deceased etc., whilst there is no pardah between the opposite sexes, intermingling etc. at those gatherings?
