To my knowledge (and I'm not one of the ones with encyclopedic knowledge), there's an international dub for every single film in the franchise, but many of those will never be seen here in the US. Notable films on that list which we'll likely never see the international dub would include:
Gojira
Godzilla Raids Again
King Kong vs. Godzilla
Mothra vs. Godzilla
Godzilla 1985
Godzilla 2000
The various cuts and edits to make the US-specific versions of those films have carried through over the years and that's the dub that has lived on in US home video releases. For pretty much all those movies above, the US version isn't JUST a straight-up dub of the Japanese cut. All except G2K add in scenes that weren't in the Japanese release and cut scenes that were, and G2K trims things and alters the score.
Anything (except G2K) from Godzilla vs. Biollante on forward IS the international dub, so you never need to bother yourself with seeking out a non-existent Titra/Titan/AIP dub.
Then there's Ghidrah, Monster Zero, Godzilla's Revenge, Gigan, Megalon, Mechagodzilla, and Terror of Mechagodzilla for which no Titra/Titan/AIP dub exists, so you don't have to fret. There are a couple unique things missing from some of these movies like title cards (Godzilla vs. Mechagodzilla has a Godzilla vs. the Cosmic Monster title card and nothing released by Sony (Gigan, Mechagodzilla) has the Japanese title card) floating around in the ether somewhere, but that won't likely affect your enjoyment of the film overall.
So what you're really left asking about are the following movies:
Godzilla vs. the Sea Monster
Son of Godzilla
Destroy All Monsters
Godzilla vs. Hedorah
These movies all had dubs done by Titra (who later became Titan) commissioned by AIP, and as of right now, VHS rips are the only surviving versions of them (aside from maybe some superfan out there having a film print somehow)...EXCEPT for Destroy All Monsters. The AIP dub of DAM was included on Media Blasters' initial pressing of the disc. Your ability to get the disc will depend on your ability/willingness to spend upwards of $50 for a movie just to get a dub.
So, a LIST of the Godzilla movies would look something like this:
1.) Gojira/Godzilla King of the Monsters (KOTM is the US version, and the Japanese Gojira with subs is available in the US - the Criterion release is likely the best version, but also available from Classic Media. Blu-ray or DVD)
2.) Godzilla Raids Again (US version and Japanese with subs available in US from Classic Media on DVD Only)
3.) King Kong vs. Godzilla (only the US version is available in the US. On DVD/Blu-ray. Japanese version not available in the US)
4.) Mothra vs. Godzilla (US version and Japanese with subs available from Classic Media on DVD only) Dub IS an AIP dub.
5.) Ghidrah the Three-Headed Monster (I'm not 100% sure if the dubbed version is US specific, though it does feature some scenes shifted around. Available dubbed and Japanese with subs. Classic Media DVD only.)
6.) Godzilla vs. Monster Zero (Dub and Japanese with subs available from Classic Media on DVD only)
7.) Godzilla vs. the Sea Monster (International version and Japanese with subs available from Kraken on blu-ray and DVD...Titra/Titan/AIP dub only surviving on VHS rips)
8.) Son of Godzilla (International version and Japanese with subs OOP on DVD in the US. If you want to spend $50+ on a Sony DVD, you can have it....Titra/Titan/AIP dub only surviving on VHS rips)
9.) Destroy All Monsters (International version and Japanese with subs available from Media Blasters on blu-ray and DVD...Titra/Titan/AIP dub available on OOP first-pressing disc)
10.) Godzilla's Revenge (Dub and Japanese with subs available from Classic Media on DVD only)
11.) Godzilla vs. Hedorah (International version and Japanese with subs available from Kraken on blu-ray and DVD...Titra/Titan/AIP dub only surviving on VHS rips)
12.) Godzilla vs. Gigan (Dub and Japanese with subs available from Kraken on blu-ray and DVD...does not include unique feature of Japanese version, which is Manga-style text bubbles above kaiju as they converse)
13.) Godzilla vs. Megalon (Dub and Japanese with subs available from Media Blasters on blu-ray and DVD)
14.) Godzilla vs. Mechagodzilla (Dub and Japanese with subs OOP on DVD in the US. If you want to spend $100+ on a Sony DVD, you can have it)
15.) Terror of Mechaogdzilla (Dub and Japanese with subs available from Classic Media on DVD only)
16.) Godzilla 1985 (Unavailable on R1 DVD/blu-ray in any version)
17.) Godzilla vs. Biollante (Dub and Japanese with subs available from Lions Gate on blu-ray and DVD)
18.) Godzilla vs. King Ghidorah (Dub and Japanese with subs available from Sony on blu-ray...DVD version is dub only and cropped to 4:3 ratio)
19.) Godzilla vs. Mothra (Dub and Japanese with subs available from Sony on blu-ray...DVD version is dub only and cropped to 4:3 ratio)
20.) Godzilla vs. Mechagodzilla II (Dub and Japanese with subs available from Sony on blu-ray and DVD)
21.) Godzilla vs. Space Godzilla (Dub and Japanese with subs available from Sony on blu-ray...DVD version is dub only)
22.) Godzilla vs. Destoroyah (Dub and Japanese with subs available from Sony on blu-ray...DVD version is dub only)
23.) Godzilla 2000 (US version and Japanese with subs available from Sony on blu-ray...DVD version is dub only)
24.) Godzilla x Megaguirus (Dub and Japanese with subs available from Sony on blu-ray and DVD)
25.) GMK (Dub and Japanese with subs available from Sony on blu-ray and DVD)
26.) Godzilla against Mechagodzilla (Dub and Japanese with subs available from Sony on blu-ray and DVD)
27.) Godzilla Tokyo SOS (Dub and Japanese with subs available from Sony on blu-ray and DVD)
28.) Godzilla Final Wars (Dub and Japanese with subs available from Sony on blu-ray and DVD)
I bolded the ones you're asking about in terms of the dubs.
As for MST3K versions, Godzilla vs. the Sea Monster has never been released, and Godzilla vs. Megalon had some weird rights thing where Rhino essentially released it (on MST3K Collection Volume 10) without permission, and so had to pull it and re-release with a different movie instead of Godzilla vs. Megalon. If you REALLY want the MST3K version of Megalon on DVD, it'll only run you $500 or more.
This discussion of course does not include any sort of downloading or what have you as such discussion is explicitly frowned upon by Monster Zero.
