New to Islam and Need Some Guidance on Salah and Du'a

Assalamu alaikum everyone! I'm a new Muslim and, honestly, I'm finding it tough to get into the routine of praying five times a day. It's a huge change for me, and staying consistent is a real struggle. I also have a few questions about salah and making du'a that I was hoping you could help with: 1. What are the best times for du'a? Since I'm working on my five daily prayers, when are the most blessed times during the day to make personal supplications to Allah? 2. Is it okay to share my du'as? If I make a specific du'a for something, can I tell my family or friends about it, or should I keep it just between me and Allah? 3. Is there strength in numbers? I've heard that when more people pray together for something, it's more likely to be accepted. Is that true in Islam? Any advice on how to stick with the five prayers and answers to my questions would mean so much. JazakAllah Khair!
