I've just done some more research here. So Hekkpipe is your brand? And you're worried that people might not know that means it's a portable (and epic by the way) sort of 'picnic / skatepark / on the go hookah'. But also you presumably don't want people thinking it's an ecig!
OK so now I understand a bit better I would certainly have Hookah in the name of the brand. Not for google for people. If you'd said right at the get-go My site 'portablehookah.com' or 'picnichookah.com' wants to do x, y and z then I'd instantly have known what it was all about.
Also - and very interestingly - I'm a dentist and have never had a dedicated page for 'Smile Makeovers' because it's broad and competes with all the elements of a smile makeover like implants and dental stuff. But we've always ranked for 'smile makeover' because our URL is 'Smileworks' Also "The Brace Place" was really hard to beat to the number one spot for 'Braces' but we did do it eventually. So i'd say you're perhaps trying to solve the wrong problem here.
Unless you are going to do multinational advertising so that the whole world knows that Hekkpipe means 'Portable Hookah' then i'd put it somewhere in there so people know what they are looking for and looking at. It's a great idea and a beautiful website but I literally wasn't sure what it was from any of your URL examples. SO why not spell it out for the masses. People are not that smart and especially in my niche we have to spell out lots of stuff that is not always the most elegant and 'cool' but it gets the job done and people understand and when they understand they buy.
Like I'd want one of these now - if I hadn't given up my ecig in favour of gum. Think about expressing your brand in terms of what you are for and also what you are against. Sometimes it's useful to say what you are not so people can better understand what you are. Does that make sense? So you are for smoking and activities and healthy outdoorsy stuff and parties and being cool. What you are not is a whole load of things that you need to spell out to the potential buyers - who maybe hookah users or ecig users or just people who like cool stuff or they may be outdoorsy types or super-cool social types.
