How Many Pokémon Can You Get with Only Pokémon Alpha Sapphire?

Assuming you do not use any glitches, the answer is 410. The Professor Oak challenge guide for Alpha Sapphire can be found here, although I've made a shorter list of encounters below in case anything happens to the external guide.

The list of Pokémon you cannot get without trading, which equals 311 species, is as follows:

Two Hoenn Starters (6) - 6 total
As you can only select one Hoenn starter Pokémon, the other two starters, and their evolutions, are unavailable; this totals 6 Pokémon.
Two Johto Starters (6) - 12 total
As you can only select one Johto starter Pokémon, the other two starters, and their evolutions, are unavailable.
Two Sinnoh Starters (6) - 18 total
As you can only select one Sinnoh starter Pokémon, the other two starters, and their evolutions, are unavailable.
Two Unova Starters (6) - 24 total
As you can only select one Unova starter Pokémon, the other two starters, and their evolutions, are unavailable.
Trade Evolutions (17) - 41 total
Golem, Machamp, Alakazam, Kingdra, Huntail, Gorebyss, Rhyperior, Dusknoir, Slowking, Steelix, Electivire, Magmortar, Porygon2, Porygon-Z, Gigalith, Conkeldurr, and Trevenant evolve by trade. Without the ability to trade, they are unobtainable.
One Fossil Pokémon (2) - 43 total
As you can only obtain one Fossil on Route 111, you miss out on the other Fossil Pokémon (Lileep or Anorith) and its evolution.
Version Exclusives (21) - 64 total
The following Pokémon cannot be obtained without the use of glitches, trading, or events: Seedot, Nuzleaf, Shiftry, Mawile, Zangoose, Solrock, Latios, Groudon, Kabuto, Kabutops, Ho-Oh, Shieldon, Bastiodon, Palkia, Throh, Archen, Archeops, Tornadus, Reshiram, Skrelp, and Dragalge.
Starter Pokémon (18) - 82 total
The Kanto and Kalos starter Pokémon must be obtained by trading from X or Y, or transferring from a previous generation.
Legendary Pokémon (10) - 92 total
Articuno, Zapdos, Moltres, Mewtwo, Giratina, Landorus, Kyurem, Xerneas, Yveltal, and Zygarde must be obtained by trading from X or Y, or transferring from a previous generation.
Mythical/Event (15) - 107 total
Outside of glitches, Mew, Celebi, Jirachi, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, Genesect, Diancie, Hoopa, and Volcanion were only obtainable via events that are no longer active, or transferring from previous generations (which requires trading).
