Help please with identification of few components for troubleshooting (Solar Water Fountain circuit)

[Techie_hobby1]

Need some help please with a few components on this small board so that I can troubleshoot the circuit.

The PCB is a Single sided board fairly simple circuitry has a +ve and -ve Solar cell power input, a 7.4v 1500mAh (dual 18630 cell) power in which the Solar panel charges the cells, and lastly the Output goes to a DC connector...
J1 is actually 1P1T Switch (in ON position completes Battery cell circuit
J2 - to DC Output
J3 is Battery cell connector

however I am struggling to identify if:
Y1 (SOT-23) are NPN Transistors, MOSFET's or 11v Zener's. I am fairly sure they are NPN Transistors though because I get a 0.6v diode reading on Collector and Emitter with +ve on Base.
Same for Y2 (SOT-23) being PNP with -ve on Base and 0.6v on Collector and Emitter.

The 8 pin IC is a little odd though but with no markings is making it a lot harder.

If I am incorrect with any of the above please can you advise further
Many thanks

Y1 = SS8050.

Y2 = SS8550.

To identify the IC, you would need to identify its pinout.

the switch has fractured soldering

Thanks as always. I think sometimes I over think it in regard to the component searching, and try to use the sites that let you search by the Marking code, instead of trying to do a standard google image search first.
In regard to the IC 8pin SOIC connections are as follows ( I think it is just 555 timer chip - but just want some clarification please):
Pins are as follows:
Pin 1 connected to Cathode of D1 diode and bridged with pin 4
Pin 4 goes to collector of PNP (Q3) transistor via current limiting resistor
Pin 2 goes to collector of NPN (Q4)and also to collector of NPN (Q1)
Pin 8 goes to Anode of the same D1 diode, to DC positive

Thank you for pointing that out. I actually didn't see that one. I think I managed to locate a few that were broken/cracked.. and still going through them slowly

whoops I forgot to include pin 7 of the IC, which connects to the base of NPN Q5 transistor
