I just went through a large lot of new and old Lego and was hoping for a little help on a few of them

are these Lego?

 

I know these are but what era?

 

I know these are 80's era light bricks, can someone point to a good resource about how these work?

 

Thanks in advance to anyone who is able to assist.

1. Technic Link Tread (3873)

2. Pickaxe (3841)

3. Wheel Cover 10 Spoke T Shape - for Wheel 18976 (18979a)

4. Round 1 x 1, 2 on a sprue (4073c01) looks like you got the sprue portion. 

5. As for the figures, those are from the 70’s. You can look under the part category of homemaker.

Thank you so much, turns out I've got a sound box too.  none of the other parts though.  I appreciate your help

Those types of lights require a 9v battery box. There are metal contacts built into the studs on the top of the box and those send the power to the light pieces.

There are also other pieces that you can connect to the box that have the metal contacts and will route the power further away.
