Wondering About Jannah as a New Muslim Brother/Sister

Assalamu alaykum wa rahmatullahi wa barakatu, dear brothers and sisters! I’ve been thinking about some stuff regarding Jannah and I’d love to hear your thoughts – may Allah subhanahu wa ta’ala bless us all with Jannatul Firdaus, ameen. If you can, please share any evidence from the Quran you know. Jazakallah khair for your time, and let's keep it all kind and respectful! [Sorry if some of these seem a bit silly, I’m just really curious and trying to learn.] 1. I get that worship isn’t obligatory there and just being in Jannah is an act of devotion, but could I still choose to do the 5 daily prayers? It’s such a part of my soul as a Muslim. 2. I’ve heard there’s a market in Jannah. How would that even work – do you buy things or is everything just given freely? 3. Will there be night and day in Jannah? I love the quiet of night, and honestly, I really hope there's rain too – the sound and smell just calm my heart deeply. 4. Big palaces and riches never interested me much. I’d rather have a home surrounded by nature, with plenty of open space, where love and peace fill the air as soon as anyone steps inside, especially when guests come over. 5. They say your friends become your neighbors in Jannah, but what if my wife has friends I’m not close to – how does that work? 6. Will I be able to chat with the angels of Jannah?
