LHF Tideway Classic Script

O...K. No font exists that will do the job as koeiekat has wisely pointed out, but you do have options for doing it yourself.
I don't use Word but, according to the MS office website, it supports Warichu (2lines leading a single line) type setting, just like the video link I gave above.
Do a little digging around (in MS Word Help) and you should be able to achieve what your after by typing your credits as a single line, then exploiting the Warichu formatting options MS Office makes claim to.

Or, you could download the 30 day trial version of Adobe Illustrator and follow Deke's tutorial video I linked to earlier

IMHO downloading the demo and following the vid are the best option.
From Illustrator you can export the set credits as a format you can drop into Word.

XeresDan. What application are you using to typing in?

Ay...DIY Job indeed. What I'm trying to establish though, is, if there's a way (such as the Warichu trick in Illustrator I linked to above) that we can make it easier to set manually for XeresDan. If we know what they're using to set the type in (Indesign, word, open office, whatever) there may be a similar tweak we can find to help out.

Steel Tongs would do the trick perfectly but I think (though my french is awful) XeresDan is asking for a French Language equivalent.
XeresDan. What are you using to create your poster (Clearly not Illustrator)?

Lubalin Graph maybe? demi? Either each letter in its own layer or (say in Illustrator) as separate elements, each with reduced opacity set.

The Nautigal

According to Cadbury web site, this logo first appeared in 1921, so will be hand lettering.

Could be Alter ego (but kind of small so hard to tell)

But you could use something like Brauhaus as a starting point

Logo. Apparently done in '79, so my best guess would be, someone with a drawing board 'n' a pen.

You could start with something like Allstar but I think the clumsy shadow effect and the spatters are custom, not font.
