Can someone please tell me how get the 3 regi and feebes I know I asked..

To begin you need the following things: Surf, Dive, Rock Smash, Dig, Flash, Wailord, Relicanth, and tons of Ultra Balls.

First, Surf on Route 134 through the currents until you find a diving spot. Use Dive and go to the cave at the bottom. Once inside, go all the way to the top and stand in the middle of the braille, read it and use Dig. You will then be sent to another cave, once inside, make sure that Wailord is first and Relicanth is last in your team, stand in the middle of the braille and press A. An earthquake will occur and you have opened up the Regi tombs.

All Regis are Lv.40

I'll start with Regirock. His cave is in the south of the desert. Once inside, go to the top in the middle of the braille. Go two steps left then two steps down and use Rock Smash. A door will open and there is Regirock.

For Registeel, his cave is SouthWest on Route 120. Inside, go to the middle of the braille, read it, then go to the center of the room and use Flash. A door should open and there is Registeel.

Lastly, for Regice, his cave is on Route 105 in the water all the way to the left. Once inside, read the braille and then do a clockwise lap around the room. A door should open and there is Regice.

As for Feebas, you need to fish (I prefer the Super Rod but you can use any you want) in the lake next to the Weather Institute on Route 119. You have to be patient though, because it only appears on 6 of the hundreds of tiles. Feel like shuffling those 6 tiles? Then change the Trendy Phrase in Dewford.
