Help identifying components

Hello.

This is a small hand vaccum cleaner PCB and the appliance happens not to being able to turn off other than to let the battery die!
I have already identified an apparently blown SM4024N CT98V FET (short between Source and Drain). But I wanted to try to check if a few other components could also be damaged. I'm heading next week to a near town where I can probably purchase these kind of items, so I wanted to try to test them prior to going to that town, but I'm struggling to identify some of them.

So, this is the board (don't worry about the lifted pad, it's from the blown FET)


Component 1 is a Q1, so it's a transistor but I can only see the following:

The other one is this:

I know this one is a diode and I can measure voltage drop of aorund 0.42V. But I couldn't find specs for it to know if this voltage drop is ok or not!

And 2 more, if anyone knows:

I already figured out one of them. The ES2G is a rectifier. I couldn't find it sooner because I was reading E52G instead!
