Case 1 : I have IOTAs on 1 address
User can't send to multiple addresses simultaneously. Private key reuse.
Case 2: I have IOTAs on multiple addresses
User can't choose the address to spend on GUI wallet.
Is it possible via API for case 2?

AFAIK, the current wallet don't support this kind of complex scenario (i.e. sending to multiple addresses simultaneously). You have to craft a proper Bundle to send funds to multiple addresses.
Case 1 :
- Assume that you have 600 iotas in <MY_ADDRESS>
- Assume that you need to send 200 iotas to Alice
- Assume that you need to send 300 iotas to Bob
You need to craft a Bundle with the following transactions in it :
<MY_ADDRESS> send 200 to <ALICE_ADDRESS>
<MY_ADDRESS> send 300 to <BOB_ADDRESS>
<MY_ADDRESS> send 100 to <MY_OTHER_ADDRESS>
You need to sign all those transaction with the private key of <MY_ADDRESS>
Case 2 :
- Assume that you have 300 iotas in <MY_ADDRESS_1>
- Assume that you have 300 iotas in <MY_ADDRESS_2>
- Assume that you need to send 200 iotas to Alice
- Assume that you need to send 300 iotas to Bob
You need to craft a Bundle with the following transactions in it :
<MY_ADDRESS_1> send 200 to <ALICE_ADDRESS>
<MY_ADDRESS_1> send 100 to <BOB_ADDRESS>
<MY_ADDRESS_2> send 200 to <BOB_ADDRESS>
<MY_ADDRESS_2> send 100 to <MY_OTHER_ADDRESS>
Of course the first transactions must be signed with the private key for <MY_ADDRESS_1> and the 2 last transactions must be signed with private key for <MY_ADDRESS_2>

1In your last example, 100 iotas are left on
<MY_ADDRESS_1>and you overspend 100 iotas on<MY_ADDRESS_2>. Are those transactions still considered valid ?– aguadoeMar 6 '18 at 14:57 -
