Hello Jitesh,
A score of 456 out of 720 is a decent one and with this score, you have a fair chance of getting a BAMS or Veterinary College under the reservation of EWS (Economically Weak Section).
You need to apply separately for AYUSH counselling (conducted by AACCC) and AIPVT counselling (conducted by VCI) in order to take admission in BAMS and BV.Sc respectively.
Here, I'm providing you the links where you can get more information on the courses of your choice.
