Three Transistor Radios to Repair

I picked these three transistor radios up in a box of junk at an auction. I have little experience with transistor radios, can I make them go again?

My Digital Signal Generator:
The Signal Generator is a project kit from a local electronics magazine called Silicon Chip, there is a sister publication in the UK called Practical Electronics, it was featured in the April 2018 edition but mine has a oscilloscope function as well which I don't use. There may be a later edition in PE with that feature.
