No you cannot catch Entei in Pokemon Emerald.

None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
you must die
Groudon, Kyogre, Latios/Latias, Rayquaza, Regirock, Registeel, Regice, Mew and Deoxys (event only's)
No you cannot catch Larvitar in Pokémon Emerald.
You can't catch a sentret in Ruby version, but you can catch one in Emerald version.
