I don't think so croydoncorgy,
The pipe from the air seperator on the left No1, is the cold feed, which is obviously blocked or water from the tank would be flooding out, the second pipe No2 is the expansion,
3 & 8 are returns.
7 is the common return to the boiler.
9 is the cylinder flow.
4 is the heating flow.
5 is the flow from the boiler.
The system is in serious need of a qualified tradesman, not least for the reasons youmentioned already.
how is the cylinder fed from the same tank or mains supply.
