It may be Pteris wallichiana C.Agardh, as the plant is so young and photographs are blur so can't confirm.
Looks more close to Pteris wallichiana C.Agardh !

Taxonomic study of Pteris tripartita and P. wallichiana (Pteridaceae) from India PIU DAS, JAIDEEP MAZUMDAR Phytotaxa Vol 414, No 1, 2019 (Abstract- Detailed morphological features and images are presented for Pteris tripartita and P. wallichiana from India, which are often misidentified and confused. Based on field observation and study of specimens, the hairy form of P. wallichiana was accepted as a distinct variety, not a synonym of P. wallichiana. The nomenclatural status of P. wallichiana was clarified. Lectotypes were selected for P. tripartita and P. wallichiana var. yunnanensis.)
