I am a 22 yr old male will stretching exercises help me grow?

No. At 22 years of age your growth plates are fused. You are done growing.
No. Any transient gain in length by stretching, hanging upside down, etc. Disappears after gravity again exerts its full effect on your body. This is a common myth but it is a myth. You quit growing taller when your growth plates fuse, at 16-17 in males, 15-16 in females. A balanced diet/rest/exercise support normal growth. If you have not grown in the past year you are done, have a good life.
