No.
No r404a is not compatible with r409a, r134a and 404a use the same lubricates and are compatible but r409a use a different lub making them incompatible
what is suction pressure of r407a
No, refrigerants cannot be blended.

R-404a is a substitute for r-22 refrigerant but requires the system to be charged with POE lubricant. R-22 is being phased out by international protocols. The two refrigerents should not be mixed, but a tiny amount of residual r-22 left in a system being recharged with r-404a (which is itself a mixture of r-125, r-143a and r-134a) will not cause any problems.
a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
