> Voice encryption/scramble on Amateur-Band's is not allowed, everything else is ok.
It seems like you're saying voice encryption is not permitted, but data encryption is? This is not true in the US. Any encoding used for the purpose of "obscuring meaning" is not permitted on amateur frequencies. Even using code phrases like "the eagle has landed" is arguably not allowed. There are some narrow exceptions for things like satellite control codes, but nothing that applies to hobby mesh nets.
> No amateur station shall transmit: [...] messages encoded for the purpose of obscuring their meaning, except as otherwise provided herein; obscene or indecent words or language; or false or deceptive messages, signals or identification.
No, numbers stations are not permitted on amateur frequencies in the US. There are some notable cases of foreign governments setting these up and interfering with amateur allocations [1], but there's not much the FCC can do about that.

Here is the relevant Part 97 rule: https://www.ecfr.gov/current/title-47/part-97#p-97.113(a)(4)
