How many private keys can a wallet have?
Two. While the public key pair allows a one to many relationship for connections, there are only two keys. Your private key, which you share with no one, and the public key, which you give to everyone. Can the same Bitcoin balance exist in more than one wallet?
1 user per private key (if you don't share it or give access to your wallet) 1 or many private keys per user. 1 private key per address (otherwise collision).
Hierarchical deterministic (HD) wallets use a single seed phrase to generate many private keys, public keys, and corresponding addresses.
The private keys are numerically identified with the related Bitcoin address which is hashed utilizing the SHA256 calculation to decrease the complete length of the bitcoin address. In Bitcoin, the private and public keys are 256-bit numbers which makes a complete number of conceivable private and public keys of 2^256.
As a user, this means you have 3 total private keys corresponding to a single Bitcoin wallet. In order to move your funds, you need at least 2 of your private keys to sign a transaction.

If you want a friend to send you money, e.g. 0,001 BTC, they will send the money to your Bitcoin wallet address you have provided them with. NOTE: Wallet address and public key are not the same, as the wallet address is the final part of the public key.
Because private keys are stored in application and device wallets, hackers can access them and steal your cryptocurrency.
When signing just sign with all the private keys, when verifying try to verify one of the signatures. Encryption is the usual operation and decrypting should try to decrypt with all the keys (one of them should work). But in the link given by Rasmus Faber above it appears that you can't have multiple public keys.
Yes, you can have two keys generate the same address. There are 2^160 possible addresses, and 2^256 possible private keys, so each address corresponds to roughly 2^(256-160)=2^96 private keys.
Private keys and personal certificates are stored in keystores. Public keys and CA certificates are stored in truststores. A truststore is a keystore that by convention contains only trusted keys and certificates.
