Need Help Identifying Components

-

i need identifying several components salvaged various devices.  sucks don't know stuff how use them/what they're for.  if put name of these components and/or give general idea of they're used appreciated.


p.s. i'm highly interested learn # 3, 6, & 7

3 - looks inductor.
6 - diode
7 - not sure, either crystal or inductive lamp or bulb or maybe fuse?

1 a. capacitor in 200v - 300v
1.b ceramic cap or maybe mov (hard tell picture, hard read writing)
1.c mov or ceramic cap,.

4 a. cap,b.relay,c. relay?
5 2watt 2ohm resistor

probably got couple wrong, 7 , 1
