Need advice on helping my circle of friends

Assalamu alaikum wa rahmatu Allah. Peace and mercy from Allah be upon you all. I need some advice about my friend group. There are five of us. Me and two other guys encourage the others to pray and try to remind them gently. Those two are overall good brothers. But there's one guy who seems to always put them down - he criticizes them a lot, and I don't think he really understands Islam well. For example, we were praying at school and were a bit late for class. Another friend came in late, and when we finished the prayer this guy got upset with me because the late friend had to make up the portion he missed. He also seems to enjoy stirring trouble and spreading negativity about those two, even trying to cause fitnah against them. Then there's the last guy, who is very different. He is really bad at hiding things and, unfortunately, the most lost person I've met when it comes to faith. He listens to music, doesn't pray, and quickly changes the subject whenever Islam is mentioned. Music is a huge part of his life - he plays a VR rhythm game that centers completely on music. He's otherwise neutral and doesn't openly hate anyone. I'm pretty close with him and the first guy, so I feel like I should be able to reach them, but I honestly don't know how. I remind myself this is a test from Allah and I want to respond correctly. I pray Allah gives me wisdom and helps me guide them, but right now I'm really unhappy with how things are. If anyone has gone through something similar or has tips on how to advise friends kindly, please share. May Allah guide us all to the straight path and make our way to Jannah easy. Assalamu alaikum wa rahmatu Allahi wa barakatu.
