Pointing - if you are talking about simply owning the domain names for offices,different product lines or so your competitors can't get them, then simply log into your domain name control panel and forward (you can also cloak the domain name so that url remains the same as the one searched for - although this sometimes will not work!) the url to the page you want shown.
You can change the forwarding at any time (should happen within a couple of hours) if and when you need. Just make sure that you never submit the domains that are being forwarded to the search engines. It will not hurt you much, but it is wise not to chance it (
pr 2/10 would be the best you could hope for and very rare) - I would suggest you only use these names in offline stationary or ads etc.
Search engine wise it would be much better to create another page off your existing site eg.
http://www.countryestatespain.com/co...ate-malaga.htm
(or variation)then optimise this page esentially for the one search term. The engines will not penalise you for pointing a parked domain at this page, nor will you get any benefit from the search engines by doing this. The benefit is only from advertising this parked domain offline ,etc (can also be used to track response rates online).
In future you should also register country-estate-spain.com as this is a much better url for search engine purposes especially google, however the importance of this is questionable in the whole scheme of things (not even a 5% boost). The domain name without hypens is read as one word by most search engines. Also your competitor could pick this domain up at any time and use it.
Final lowdown is this - you wont be penalised for spam by pointing parked domains to your 'live' site - just don't submit the parked domains otherwise I wouldn't be confident with the outcome. Second - you talk of many pages with many domains - start thinking separate hosting accounts, domains and sites and you will be heading along the right path - but that's another story!
