The Arabic word ینزل has two meanings: یَنزِلُ, from the bab of Darb, meaning "to descend," and یُنزِلُ, from the bab of If'al, meaning "to send down." With a fatha on ز, ینزل is the passive form from the bab of If'al. As for Yanzalah (ینزلة), this word is meaningless and is not used in Arabic at all.
It is therefore better to choose a name from among the names of the Sahabiyat, may Allah be pleased with them all. The Prophet ﷺ counted giving children good names as one of the rights children have over their parents.
One hadith states: Hazrat Ibn Abbas, may Allah be pleased with him, narrates that the Sahabah al-Kiram, may Allah be pleased with them, said: "O Messenger of Allah, we have learned what rights a father has over his child. Tell us, what rights does a child have over the father?" The Prophet ﷺ replied: "The father must give the child a good name and raise them with good character and manners."
Allah the Almighty knows best.

عِنِ ابْنِ عَبَّاسٍ رضی اللہ عنہ :أَنَّہُمْ قَالُوْا یَا رَسُوْلَ اللّٰہِ! قَدْ عَلِمْنَا مَا حَقُّ الْوَالِدِ عَلَی الْوَلَدِ فَمَا حَقُّ الْوَلَدِ عَلَی الْوَالِدِ؟قَالَ أَنْ یُحْسِنَ اِسْمَہ‘ وَیُحْسِنَ أَدَبَہ‘۔
