#1 is a call

As for #2, I have seen many dealers allow it to be a raise, if it was clearly their intention. I'm pretty sure this is incorrect though.

I think the rulings would be as follows...
Next player tosses out:
a)1 $5 chip = call unless he was unaware of the raise
b)2 $1 chips = no action, he was unaware of the raise
c)1 $25 chip = call
d)1 $1, 1 $25 chip = raise to $26
e)2 $5 chips = call
f)1 $1, 2 $5 = raise to $11
