Is there a way to get to the hash160 address from bc1q34aq5drpuwy3wgl9lhup9892qp6svr8ldzyy7c
Yes, you could use the reference implementations in various languages to encode and decode a bech32 address. For example, I have decoded the sample address you mentioned in the question, bc1q34aq5drpuwy3wgl9lhup9892qp6svr8ldzyy7c, using python below. The decode ...

The blockchain does not see wallets at all. It only sees spent and unspent transaction outputs (txouts). A txout is either completely spent or completely unspent - it cannot be "partially" spent and so there is no notion of balance. (If you want to spend less than the full value of a transaction, you create a change output.)
In your example, there are ...

Bitcoin does not work on an account model but operates on an UTXO (unspent transaction output) model. When you send bitcoins to an address, what you are essentially doing is locking those bitcoins in a mathematical equation. Spending those coins requires that you provide the correct unlocking condition (most often signature and public key associated with ...

No, you cannot assume this.
There are a number of ways in which individual inputs may belong to different wallets/owners. For example:
They could come from a hosted wallet or exchange, where inputs may span coins deposited by thousands of individual users, and selected for a transaction with no particular relation to the user making that transaction

As per BIP 173, the data part consists of:
The data-part values:
1 byte: the witness version
A conversion of the 2-to-40-byte witness program (as defined by BIP141) to base32:
Start with the bits of the witness program, most significant bit per byte first.
Re-arrange those bits into groups of 5, and pad with zeroes at the end if needed.
Translate those bits ...

It is a left over API design from bare multisig transactions.
The example you provided is a P2SH multisig - in this, the actual output script has no way of telling Bitcoin Core that it is a multisig output. It can be any script. Thus, Bitcoin Core just decodes it to a regular P2SH address.
Although no longer commonly used, there are also bare multisig ...

Bitpay/Copay use Hierarchical Deterministic wallets so you can find all the adresses that has been generated from your root private key (seed recovery phrase)
