1. I don't see anything obviously wrong with your DH parameters
2. I would agree with @heaven that you are in a singular position. Which will lead to the inverse kinematics failing. In your pictures j5 is collinear with j3. Trying a different start position for j4 should help.
Thanks @Aciera
Finally got it working. Added Home Offset and Home Values to Joint_1 since it was not aligned as in documents and I cant give my arm that postion due to its hardware limits. So Accordingly defined Home and HomeOffset. and Small offset to J2 so that I remain horizontal. And minor offsets to J4. and Assiged Home location of J4 so that it remains vertical.
Thanks a lot.
Yes as @Aciera mentioned DH parameters are good.
