The peak voltage of 110VAC is 155V. If it rises to 120V then the peak voltage is 170V. Spikes might increase the peak to 380V.
A 1N4001 has a max allowed voltage of only 50V. Use 1N4004 diodes rated at 400V.
Look at the datasheet for a 7805. Texas Instruments recommends a max input of 25V. Of course the voltage across it times the current through it determines how hot it will get.

I agree with all that audioguru has mentioned, but you are not rectifying the mains directly, you are using a step down transformer, so the voltages mentioned will be substantially lower. Regardless, it would be better to over engineer the bridge, even if the 4001s work.

Audioguru's comment is still valid.
there is no need to make two doors for cat and kitten as the old story went. 1N400x7 can be well used for most jobs whether you make a bridge for 9V Ac or 110 /220V AC. This helps need for ordering separately for low voltage needs. Otherwise, courier companies benefit.
