We have no idea. Since the Triangulum galaxy is quite distant, we certainly cannot see any individual planets; we cannot even see individual STARS at that distance unless they are quite bright.
We can GUESS; for the nearby stars that we have studied using the Kepler Space Telescope, we seem to be averaging about one planet per star. The Triangulum Galaxy, M33, is somewhat smaller than the Milky Way or the Andromeda Galaxy, and Wikipedia estimates it at perhaps 40 billion stars, and estimate that is probably quite low. (We are discovering that there are far more of the small dim stars around than we had expected.) So a reasonable first approximation for the number of planets present there would probably be somewhere on the order of 100 billion.
But that's a GUESS.

Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
Since a galaxy can have many solar systems and a solar system might have more than one planet, for each galaxy there would be many planets. Therefore there would be more planets than galaxies.
As a matter of fact, yes. It has planets just like the Milky way galaxy.
We can't even see individual STARS in other galaxies, much less PLANETS. We have no idea how many stars are there.
That doesn't make sense - there is not "a" triangulum galaxy, it is "the" triangulum galaxy. In other words, this is the proper name of one specific galaxy.
The galaxy Triangulum is like the Milky Way and Andromeda galaxies a Spiral Galaxy
400,000,000,000.
Triangulum is the constellation between Aries the Ram and Andromeda. It's also the name of a spiral galaxy - it's named The Triangulum Galaxy because it's found in the Triangulum Constellation.
The Andromeda Galaxy, and the Triangulum Galaxy.
Canis Major Dwarf Galaxy. If you meant what's the closest spiral galaxy, then the answer is the Triangulum Galaxy.
It is spiral barrered
The name tells us that it is in the Triangulum constellation. That indicates the general direction. Also, the Triangulum Galaxy is approximately 3 million light-years away - fairly close for a galaxy. In other words, it is part of the Local Group.
Two nearby galaxies are Andromeda galaxy and Triangulum galaxy. Andromeda galaxy is about 2.56 million light years away from us. Triangulum galaxy is about 3 million light years away from us.
The Triangulum Galaxy (also known as M33 and NGC 598) is a spiral galaxy 3 million light-years from Earth in the Triangulum constellation, and is 60,000 light-years in diameter, and contains 40 billion stars.
Messier 33 (M33), or NGC 598.
There are billions of planets and moons in the Star Wars galaxy.
