Pokemon prism is a hack game based off of the Gold version Pokemon game. As of yet I have not found any list of Pokemon that are even in the game and there is a chance that it wasn't added to it.
you cant, charmander is not in platinum
You cannot catch it in platinum but only in ruby, sapphire and emerald.
you cant catch it in emerald
No
You can catch more legendary pokemons on platinum. So you can catch more on Platinum, then the other games :)
you cant catch an executor, but if you get an exeggcute from the great marsh and level it up, you can use a leaf stone on it to get it to evolve into an executor
You can find Exeggcute in the Great Marsh.

You can find exeggcute in the Great Marsh in Pastoria City
NO! I'm telling the truth! Exeggcute are caught in the Safari Zone, or Headbutt Trees! DO NOT DELETE THIS ANSWER!
Crystal Spearow Exeggcute
Safari Zone
You can't catch Exeggcute on Pokemon Sapphire. You need to trade one from Fire Red or Leaf Green.
you can't trade from pal park
in the sinnoh reigon chatot in the national exeggcute
You'll find a lot of them nothwest of ecruteak city
To catch an Exeggcute, you have to headbutt trees in places like Ilex forest or trees by the roadside. you can get headbutt (TM02) from a guy in Ilex or you can buy it from Goldenrod Department store for $2000. I hope it's useful. :)
