If you only have to care about an empty last field, then using sed would be shorter:

$ sed 's/:$//; s/:/ + /g' file
Hello + world
Hello + worlds
Hello + world + example

---

Your attempted awk command can be salvaged like this:

$ awk -F":" ' print $1 " + " $2 ($3 != "" ? " + " $3 : "") ' file
Hello + world
Hello + worlds
Hello + world + example

Or, by using OFS (the output field delimiter):

$ awk -F":" -v OFS=' + ' ' print $1, $2 ($3 != "" ? OFS $3 : "") ' file
Hello + world
Hello + worlds
Hello + world + example

If last column is empty, remove last column from output.

awk '$NF=="" NF-- $1=$11' FS=':' OFS=' + ' file

Output:

Hello + world
Hello + worlds
Hello + world + example
