Answer 1

What you do in this situation, is split the file into parts. 
Start with:
set theHours to hours of the (current date)
if theHours > 18 then
          say "good evening sir"
else if theHours > 12 then
          say "good afternoon sir"
else if theHours > 6 then
          say "good Morning sir"
else if theHours > 0 then
          say "get out of bed sir!"
end if
Add in a few lines of code to this file and see what happens. 
add the on run, this would be clearer.  It is the default on unit to run.
on run
    set theHours to hours of the (current date)
    if theHours > 18 then
        say "good evening sir"
    else if theHours > 12 then
        say "good afternoon sir"
    else if theHours > 6 then
        say "good Morning sir"
    else if theHours > 0 then
        say "get out of bed sir!"
    end if
end run
Now, it is time for debugging.
It is easier to diagnose problems with debug information. I suggest adding log statements to your script to see what is going on.  Here is an example.
    Author: rccharles
    For testing, run in the Script Editor.
      1) Click on the Event Log tab to see the output from the log statement
      2) Click on Run
on run
    -- Write a message into the event log.
    log "  --- Starting on " & ((current date) as string) & " --- "
    --  debug lines
    set desktopPath to (path to desktop) as string
    log "desktopPath = " & desktopPath
end run
