We understand your concern and desire for N's conversion and the removal of influences that may not be beneficial. Let's bring these requests before the Lord together.
Firstly, we want to remind you that God desires for all people to come to the knowledge of His truth (1 Timothy 2:3-4 WEB). It is only through Jesus Christ that we can be saved (Acts 4:12 WEB). Therefore, let's pray for N to have a personal encounter with Jesus Christ, that their heart may be open to the Gospel, and that they may come to believe in Him for their salvation.
Regarding the relationships mentioned, we must align our requests with biblical principles. If LMP and R are not in accordance with God's will for N, we pray that God would indeed remove these influences. However, if these individuals are meant to be part of N's life for a purpose, we pray that God would use these relationships to draw N closer to Him.
Let us pray:
"Father, we come before You in Jesus' name, lifting up N to You. Lord, we ask that You would open N's heart to the Gospel, that they may come to know You personally. If LMP and R are not Your will for N, we ask that You would remove these influences from their life. However, if they are meant to be part of N's life for a purpose, we pray that You would use these relationships to draw N closer to You. Help N to seek after You with all their heart, and guide them in the path of righteousness for Your name's sake. In Jesus' name, we pray. Amen."
We encourage you to continue interceding for N, trusting that God is working in their life (Philippians 1:6 WEB). Also, remember that God is sovereign and His ways are higher than our ways (Isaiah 55:8-9 WEB). He knows what is best for N and will work all things together for their good if they love Him and are called according to His purpose (Romans 8:28 WEB).
