Answer 1

Is ".txt" relevant? Then try:

find  ./  -regextype posix-extended -regex '.*[a-zA-Z]+.*[0-9]+\.txt' -exec <your stuff>

Answer 2

This looks like a simple example:

find ./ -name "[a-zA-Z]*[0-9]*"

Every file here needs to start with a letter 'a'-'z' (small or large caps) and somewhere in the filename you need a digit [0-9] .
