Is there are better component to use rather than multiple diodes?
1N4001 diodes are quite chunky rectifier diodes.  They should work fine, but are a bit over-the-top for your application.  On the plus side, they are extremely cheap.
If you want less voltage drop across the diodes, then Schottky diodes only drop about 0.2V, rather than 0.6V for a standard silicon diode.
If you want smaller diodes, then go for a small silicon signal diode, rather than a rectifier diode.
