Canadian Artillery Badges - Family

Ladies & Gents,
Would appreciate your learned opinions on these, i have checked the forums albums but didn't realise the minor differences in each badge, I've seen a couple similar but not my area of expertise. So what am i hoping for, i would like to attribute these to members of the family:

1) Lt, Cdn Arty WW1, served imperial artillery before for 2 years
2) BQMS, Cdn Arty WW1, served imperial artillery before for 22 years
3) Cpl, Cdn Arty, WW2, did spend time in UK.

Firstly do the badges 'fit', they have come from across the family.
Secondly, which is which?

Many thanks - Mark
