Dynamic htaccess code for multiple php parameters to friendly urls - apache

Question

I have searched and searched for an answer to this, but none of the posts I've found on stackoverflow work for me - nor do the online htaccess generators.
I have made slight adjustments to Anubhava's excellent answer on htaccess redirect for dynamic urls not working to suit different page names as follows:
RewriteEngine On
# for external redirection from `/hp.php?su=sitename` to `/sitename`
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+hp\.php\?su=([^\s&]+) [NC]
RewriteRule ^ /%1? [R=301,L]
# for internal redirection from `/sitename` to `/hp.php?su=sitename`
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ /hp.php?su=$1 [L,QSA]
However, in addition to sending users to domain.com/sitename (which the modified code above does) I also want to change the following urls.
domain.com/newpage.php?su=sitename&PgID=1234&pu=pagename
to become
domain.com/sitename/1234/pagename.html
similary
domain.com/diary.php?su=sitename
to become
domain.com/sitename/diary.html
This last one would be replicated for similar dynamic pages, such as
future.php?su=sitename >> domain.com/sitename/future.html
photos.php?su=sitename >> domain.com/sitename/photos.html
etc
Some time in the future, I would also like to divert http:// to https:// - would this rule go before all the others?
Hope somebody can help
UPDATE:
RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/hp\.php\?su=([^\s&]+) [NC]
RewriteRule ^ /%1? [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/newpage\.php\?su=([^\s&]+)&PgID=(\d+)&pu=([^&\s]+) [NC]
RewriteRule ^ /%1/%2/%3.html? [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/(diary|future|photos)\.php\?su=([^\s&]+) [NC]
RewriteRule ^ /%2/%1.html? [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ /hp.php?su=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(diary|future|photos).html$ /$2.php?su=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(\d+)/(.+)\.html$ /newpage.php?su=$1&PgID=$2&pu=$3 [L,QSA]

Answer 1

It isn't all that difficult to derive from the previous rule:
RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/hp\.php\?su=([^\s&]+) [NC]
RewriteRule ^ /%1? [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/newpage\.php\?su=([^\s&]+)&PgID=(\d+)&pu=([^&\s]+) [NC]
RewriteRule ^ /%1/%2/%3.html? [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/(diary|future|photos)\.php\?su=([^\s&]+) [NC]
RewriteRule ^ /%2/%1.html? [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ /hp.php?su=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(diary|future|photos).html$ /$2.php?su=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(\d+)/(.+)\.html$ /newpage.php?su=$1&pgID=$2&pu=$3 [L,QSA]
As to your second question about http to https, yes; that particular redirection should occur before all others.
