Is it not possible to verify positional characters without storing in plain text ?

off the top of my head, something like storing your full password salted + hashed along side each char salted + hashed.

If you store an individual character hashed then it is trivial to brute force it. I don't think there is a bcrypt work factor that you could use that would prevent brute forcing but would allow the individual character to be used for authentication.
And if you know the first character of a two character password, it's trivial to brute force the second, and so on...
i would definitely expect it to be less secure, but not exactly plain text?
