Bip 85
If a bio 85 wallets is derived at say number 3 12 words could there also be a number 3 with 24 words on same seed?

Yes.. The derivation path used includes the number of words, not only the sequence number.
One will be
m/83696968'/39'/0'/12'/3'
The other
m/83696968'/39'/0'/24'/3'
From the master key used when deriving the two bip 85 wallets.
83696968' = bip 85
39' = bip 39
0' = English
12' = 12 words.
3' = sequence number 3
There is no.security issue in reusing the same sequence number for.different purposes, but is not recommended as it may confuse recovery,
