you have to get sneasol by trading in leaf green. You can not get that Pokemon in firered.
Unless cheats are used, Charmander can't be caught in Pokemon Diamond. Charmander, however can be obtained with other methods: -Trading with a friend -Transferring it from FireRed or LeafGreen -Obtaining it from Mystery Gift -Obtaining it in either HeartGold or SoulSilver, and then trading it over.

by trading
no
You can but only from trading with Pokemon emerald or Pokemon colosseum.
By trading and catching them i think
Chinchou is not available in Pokemon Firered Version. You can only get it by trading from Pokemon Ruby / Sapphire / Emerald Version.
no sorry
You can get Charmander in Pokemon Sapphire by obtaining it in Pokemon FireRed or LeafGreen and trading it to Sapphire. To have Charmander registered in the Sapphire PokeDex, you must defeat the Elite Four. You may have the Charmander before that, but it won't register in the PokeDex.
No. The ONLY way to get Pokemon from Pokemon firered is migrating.Go to Pal Park once you have completed the game to migrate.
Only by trading from LeafGreen and/or FireRed
